Sure.

Eglot: code completion, navigation, show method docs, calltips.
TreeSitter: syntax highlighting, maybe indentation and imenu.

So TreeSitter can help improve the "classic" features of major modes, 
but not build code intelligence on top, because it only works with 
individual files, just like existing major modes and their regexp based 
parsers (in font-lock, etc).

Above, I was talking solely about tree-sitter.

I think the issue is going to be how well each mode integrates with 
tree-sitter. Those that do it well, can enable it by default right away. 
Those that don't will have different problems.

So it's not like we'll be able to decide that we're fine with a certain 
class of limitations, so let's enable it wholesale.

And there will always remain major modes that don't have tree-sitter 
integration.
