Could Ruff eventually be used alone without Pylance?

I have read #16089 and Ruff features.

But it will be fantastic if Ruff supports more LSP features [1][2] and even replace Pylance.

You know Pylance is relatively slow and not stable.

ty would probably (eventually) be the more appropriate thing to replace pylance over ruff. As it states very clearly across your 2 links, ruff is just a linter and formatter.
What you're looking for (which I can only guess since you don't go into detail), things in pylance like type checking (technically comes from pyright), semantic highlighting, diagnostics, renaming functions/variables, those are all features of a more fully fledged language server. which is what ty is.

In the meantime, if you want to ditch pylance, there are alternative, production ready python language servers. basedpyright is specifically intended to be something of a pylance alternative.
