Yes! I love to do transformations with lib2to3, but unfortunately it is now deprecated. As I've stated in the README, for complex refactorings I also would personally prefer working with CST (probably through parso instead of regular lib2to3), but for refactoring small fragments I wasn't able to observe major differences in formatting in big codebases. Thanks for sharing this btw!

Ah I didn’t know it was deprecated, but good to see new work happening in this area!
