Not sure whether this has been mentioned: there is a "treesit-auto"[1]
addon on melpa that can detect missing treesitter grammars and handle
their installation automatically.  It would be great if something
similar can be integrated into core, and if possible, grammar version
handling and compatibility with distribution supplied grammar would be
good to have.
