Thank you for summarising the situation!

It's not yet clear to me how to handle (python) package updates:
- when to update;
- when not to update;
- when to introduce "versionned" (`-x.y` suffix) package definitions;
- when to introduce "next" (`/next` suffix) package definitions;
- when to remove the two above suffixes;
- …

So I'm looking forward to reading the answers to this thread! :-)
