+# Summary
+
+The “RFC” (request for comments) process is intended to provide a
+consistent and structured path for major changes and features to enter
+the Guix project, so that all stakeholders can make decisions
+collectively and be confident about the direction it is evolving in.
+
+# Motivation
+
+The current way that we add new features to Guix has been good for early
+development, but it is starting to show its limits as Guix becomes a
+broadly used system with many contributors. Changes might be slowed down
+by the lack of structure to acquire consensus, lack of a central place
+to consult contributors and users, and lack of clear deadlines. This is
+a proposal for a more principled RFC process to make it a more integral
+part of the overall development process, and one that is followed
+consistently to introduce substantial features.
+
+There are a number of changes that are significant enough that they
+could benefit from wider community consensus before being introduced.
+Either because they introduce new concepts, big changes or are
+controversial enough that not everybody will consent on the direction to
+take.
+
+Therefore, the purpose of this RFC is to introduce a process that allows
+to bring the discussion upfront and strengthen decisions. This RFC is
+used to bootstrap the process and further RFCs can be used to refine the
+process.
+
+It covers significant changes, where “significant” means any change that
+could only be reverted at a high cost, or any change with the potential
+to disrupt user scripts and programs or user workflows. Examples
+include:
+
+-   changing the \<package\> record type and/or its interfaces;
+-   adding or removing a 'guix' sub-command;
+-   changing the channel mechanism;
+-   changing project policy such as teams, decision-making, the
+    deprecation policy or this very document;
+-   changing the contributor workflow and related infrastructure
+    (mailing lists, source code repository and forge, continuous
+    integration, etc.)
+
+For concrete past examples where this RFC process would be helpful:
+
+-   Removing input labels from package definitions, #49169
+-   Add \'guix shell\' to subsume \'guix environment\', #50960
+-   Trustable \"guix pull\", #22883
+-   Add \"Deprecation Policy\", #72840
+-   Collaboration via team and branch-features, several places over all
+    the mailing lists.
+
+# Detailed design
+
+## When to follow this process
+
+This process is followed when one intends to make “substantial”
+changes to the Guix project. What constitutes a “substantial” change
+is evolving based on community norms, but may include the following.
+
+-   Changes that modify user-facing interfaces that may be relied on
+    -   Command-line interfaces
+    -   Core Scheme interfaces
+-   Big restructuring of packages
+-   Hard to revert changes
+-   Governance and changes to the way we collaborate
+
+Certain changes do not require an RFC:
+
+-   Adding, updating packages, removing outdated packages
+-   Fixing security updates and bugs that don’t break interfaces
+
+For general day-to-day contributions, please follow the regular process
+as described by manual sections “Submitting Patches”, “Reviewing the
+Work of Others”, “Teams” and “Making Decisions”.
+
+A patch submission that contains any of the aforementioned substantial
+changes may be asked to first submit a RFC.
+
+## How the process works
+
+1.  Clone <https://git.savannah.gnu.org/git/guix.git>
+2.  Copy rfc/0000-template.org to rfc/00XY-good-name.org where good-name
+    is descriptive but not too long and XY increments
+3.  Fill RFC
+4.  Submit to guix-patches@gnu.org
+5.  Announce your RFC to guix-devel@gnu.org
+
+Make sure the proposal is as well-written as you would expect the final
+version of it to be. It does not mean that all the subtilities must be
+considered at this point since that is the aim of review discussion. It
+means that the RFC process is not a prospective brainstorming and the
+proposal formalize an idea for making it happen.
+
+The submission of a proposal does not require an implementation.
+However, to improve the chance of a successful RFC, it is recommended to
+have an idea for implementing it. If an implementation is attached to
+the detailed design, it might help the discussion.
+
+At this point, at least one other person must volunteer to be
+“co-supporter”. The aim is to improve the chances that the RFC is both
+desired and likely to be implemented.
+
+Once supporter and co-supporter(s) are committed in the RFC process, the
+review discussion starts. Publicizing of the RFC on the project’s
+mailing list named guix-devel is mandatory, and on other main
+communication channels is highly recommended.
+
+After a number of rounds of review, the discussion should settle and a
+general consensus should emerge. Please follow the “Decision Process”
+and “Timeline” sections.
+
+A successful RFC is not a rubber stamp, and in particular still does not
+mean the feature will ultimately be merged; it does mean that in
+principle all the participants have agreed to the feature and are
+amenable to merging it.
+
+An unsuccessful RFC is **not** a judgment on the value of the work, so a
+refusal should rather be interpreted as “let's discuss again with a
+different angle”. The last state of an unsuccessful RFC is archived
+under the directory rfc/withdrawn/.
+
+## Co-supporter
+
+A co-supporter is a contributor sufficiently familiar with the project's
+practices, hence it is recommended, but not mandatory, to be a
+contributor with commit access. The co-supporter helps the supporter,
+they are both charged with keeping the proposal moving through the
+process. The co-supporter role is to help the proposal supporter by
+being the timekeeper and helps in pushing forward until process
+completion.
+
+The co-supporter doesn’t necessarily have to agree with all the points
+of the RFC but should generally be satisfied that the proposed additions
+are a good thing for the community.
+
+## Timeline
+
+The lifetime of an RFC is structured into the following recommended
+periods:
+
+submission (7d) ⟶ comments (30--60d) ⟶ last call (14d) ⟶ withdrawn OR
+final
+
+The author may withdraw their RFC proposal at any time; and it might be
+submitted again.
+
+### Submission (up to 7 days)
+
+The author submits their RFC proposal as a regular patch and look for
+co-supporter(s). See “Co-supporter” section.
+
+Once the RFC is co-supported, it marks the start of a discussion period.
+
+### Comment (at least 30 days, up to 60 days)
+
+The comment period starts once the author publishes their RFC to
+guix-devel, then the proposal is freely discussed for a period of at
+least 30 days. It is up to the supporter and co-supporter(s) to ensure
+that sufficient discussion is solicited. Please make sure that all have
+the time and space for expressing their comments. The proposal is about
+significant changes, thus more opinions is better than less.
+
+The author is encouraged to publish updated versions of their RFC at any
+point during the discussion period.
+
+Once the discussion goes stale or after 60 days, the author must
+summarize the state of the conversation and keep the final version.
+
+It moves to the last call period.
+
+### Last call (up to 14 days)
+
+The author publishes a final version of the RFC and a last grace period
+of 14 days is granted. People are asked to agree or disagree by
+commenting:
+
+-   +1 / LGTM: I support
+-   =0 / LGTM: I will live with it
+-   -1: I disagree with this proposal
+
+At least half of people with commit access must express their voice with
+the keys above during this last call. We need to be sure that the RFC
+had been read by people committed to take care of the project, since it
+proposes an important change.
+
+When a positive consensus is reached, the RFC becomes effective. If not,
+the proposal is archived and the status quo continues.
+
+## Decision making: consensus
+
+It is expected from all contributors, and even more so from committers,
+to help build consensus and make decisions based on consensus. By using
+consensus, we are committed to finding solutions that everyone can live
+with.
+
+It implies that no decision is made against significant concerns and
+these concerns are actively resolved with proposals that work for
+everyone. A contributor, without or with commit access, wishing to block
+a proposal bears a special responsibility for finding alternatives,
+proposing ideas/code or explaining the rationale for the status quo.
+
+To learn what consensus decision making means and understand its finer
+details, you are encouraged to read
+<https://www.seedsforchange.org.uk/consensus>.
+
+## Merging the outcome
+
+Once a consesus is made, a committer should do the following to merge
+the RFC:
+
+1.  Fill in the remaining metadata in the RFC header, including links
+    for the original submission.
+2.  Commit everything.
+3.  Announce the establishment of the RFC to all.
+
+## Template of RFC
+
+The structure of the RFC is captured by the template; see the file
+rfc/0000-template.txt. Please use Markdown as markup language.
+
+## Backward compatibility
+
+None.
+
+## Forward compatibility
+
+The RFC process can be refined by further RFCs.
+
+## Drawbacks
+
+There is a risk that the additional process will hinder contribution
+more than it would help. We should stay alert that the process is only a
+way to help contribution, not an end in itself.
+
+Of course, group decision-making processes are difficult to manage.
+
+The ease of commenting may bring a slightly diminished signal-to-noise
+ratio in collected feedback, particularly on easily bike-shedded topics.
+
+## Open questions
+
+There are still questions regarding the desired scope of the process.
+While we want to ensure that changes which affect the users are
+well-considered, we certainly don’t want the process to become unduly
+burdensome. This is a careful balance which will require care to
+maintain moving forward.
