We will merge the tree-sitter branch to master, but Emacs 29 release
is still several moons ahead, and the master branch is used for
developing Emacs, including low-level stuff, all the time.

IOW, the fact that the tree-sitter support is still in flux is normal
and should not preclude us from landing it on master.  And if we want
it to be part of Emacs 29, we cannot wait any longer.

It is stable enough to have it on master, yes.  Not stable enough to
release Emacs with it, but then Emacs 29 as a whole is nowhere near
that status, either.
