I think step 1 is to set up the Emacs codebase so that  
people packaging emacs for the various linux distros build an Emacs
out-of-the-box with Tree Sitter bits included. That necessarily means
bundling some of the grammars in the interim. If the  Emacs that comes
with the various distros doesn't support Treesitter in a usable form,
the functionality will remain limited to hackers who build Emacs from
source and in the bigger picture --- that is small.
