No one seriously proposed getting rid of what CC Mode does now in the
areas of fontification and indentation.  What's currently on the table
is to provide optional behavior based on tree-sitter, and let users
try that and us collect feedback and decide how to develop Emacs in
these areas in the future.  I hope we will be able to start that in
Emacs 29.

No such assumptions or decisions are expected any time soon, so
everyone can stop holding their breath and start breathing again.
