I heard that it’s in a few days (from Eli). I believe the idea is that
no more new features could be added to emacs-29 branch, only bug fixes.
This actually should’ve happened when emacs-29 was cut, but tree-sitter
features had an exemption because it was merged relatively late.

I’m working on python and javascript. Newer modes I think more or less
follows the "standard list" since they are created after the discussion
of that list.

I applied your patch, with some modification (so it aligns with the
standard list). Looking at the bug report, I must’ve forgot to reply to
you after I made the change. That’s my fault.

To make features of each tree-sitter major mode more consistent. We
wouldn’t want features that has the same name but different meaning, or
features of the same meaning but different name.

Ideally all the built-in major modes.

I’m merely suggesting potential improvements to csharp-ts-mode.  As the
maintainer of it, whether it is possible or desirable to make the
changes will be your call ;-)

The initial discussion happened on here:

https://lists.gnu.org/archive/html/emacs-devel/2022-11/msg01544.html

I just posted a general call to standardize major mode font-lock
features, which stirred up a new discussion about the standard list (as
discussion on mailing lists go :-), it started at here:

https://lists.gnu.org/archive/html/emacs-devel/2022-12/msg01202.html

Maybe I should CC people that would be interested in such discussion.

Your doubts are completely reasonable. As I said, you are the maintainer
of csharp-mode.el, not me, so you can regard my words as a suggestion
rather than request. (Or perhaps nice suggestive request ;-)
