Eli, what's your solution for the problem, then?

E.g. js-mode enables tree-sitter, and installs some stuff based on it.

But js2-mode inherits from js-mode (meaning, it will run the same setup 
code, and then some of its own), yet it has its own parser. Which will 
cause all sorts of conflicts with tree-sitter.
