Yes, for sure that should be improved.

But the watches that the client are could also be reduced, perhaps. Maybe,
depending on the use case, it makes sense to only watch files on behalf of
the LSP that Emacs is actually visiting (Eglot doesn't do that, but maybe
it could). All depends on the use case, and that's what I'm interested in.
