That is highly regrettable.  You are a valued member of our team, and
it's sad to see you go.

From my point of view, we are still in early days when it comes to the
new tree-sitter modes.  For starters, we do not recommend them by
default, and some language modes are also not yet ready for prime-time.
I'm not even sure that a majority of distros ship the feature in a
useful form yet, but I didn't really check.

AFAIU, the purpose of `major-mode-remap-alist` is to provide a mechanism
to respect what users want.  Where there is disagrement, it concerns the
technical details of how to best achieve that, and to which extent we
should set things up automatically based on indicators such as the user
actions "running a mode", "loading a file", or "running a command".

But the feature has teething problems.  My understanding was that we
agreed in Bug#74339 that the situation in Emacs 30 is already better
than in Emacs 29, and that we will continue working on this in Emacs 31.

For example, it has been suggested that we should replace the automatic
setting of `major-mode-remap-defaults` with an entirely new command like
`foo-ts-mode-prefer`, that would be used as the canonical indication
that a user wants to use the tree-sitter mode everywhere.  There surely
exist other options that we could evaluate also.

For this reason, I hope that there is still room to reconsider your
decision to resign.

This is where I have to disagree quite strongly.  I find the charges
directed at Stefan Monnier both unfair and one-sided.  I fail to see
which of his actions or words that could possibly warrant such a
negative interpretation, or that would justify assuming any ill intent.

I have to agree with Eli.  Although it would, in hindsight, certainly
have been better to discuss these particular changes in more detail in
advance, I don't see that he has done anything very unusual or different
from what most other core contributors do on a routine basis.

I also do not appreciate where it veers into ad-hominem, such as talking
about Stefan M's character, etc.  That is strictly off-topic here, as
you well know, and does not reach the usual high level of standard that
one would expect from one of your posts.

Can we please all remember that we share the same goal here; that we all
want to help advance Emacs and free software?

Thanks for continuing to maintain CC-mode, and likewise.

I hope that you will seriously consider the idea to reverse your
decision to quit Emacs development.  It would be much better if we could
find a way where we can all continue working together.  I'd suggest
giving the idea at least a couple of days to fully consider, though I'll
of course respect your decision either way.

Meanwhile, if there is anything I can do to help improve things, please
feel free to reach out.  Thanks again for all your work on Emacs.
