I updated a ~3k line Python project with this the other day. I was using v0.15.x beforehand. It didn't take too long and the new rules do improve code quality. It caught quite a few things previous versions didn't.

Here's a few commits of changes:

(A whole bunch of manual changes based on its suggestions) https://github.com/nickjj/plutus/commit/9af66d31f98bef841588...

(Re-enable line length) https://github.com/nickjj/plutus/commit/21789f89bbcee37913c1...

(Force _ prefix for unused variables) https://github.com/nickjj/plutus/commit/a272c77b932e1c78558a...

(Auto-corrected by Ruff) https://github.com/nickjj/plutus/commit/6fe69cf88385ebdf9b8c...
