I'm really excited for this.
Yes, pyright is fast enough, 99% of the time. But the install story, requiring npm etc, is a bit of a pain.
A rust based version with similar install ease as ruff would be great.
Additionally, if it is a lot faster, I think it should unlock more possibilities for eager search to improve the lsp.
Quite often the pyright lsp doesn't find auto imports - there's just too much many places to search.
I'm following this with great interest!
