Ah yes, I’ve seen it. I think the part that automatically downloads and builds 
language definitions is very useful. It cannot be in Emacs core because we 
cannot distribute language definitions, but it could be a very useful ELPA or 
MELPA package. The part that automatically generate highlighting is also 
useful, but I’m not sure how would we use it. We probably don’t want to add a 
tree-sitterify-mode that just enables tree-sitter highlight in a mode—I prefer 
that we change each major mode to use tree-sitter features.

Also I think it makes more sense if you just fork it rather than making a PR.
