Thanks! This first pass I'll review manually, so it may take some time (perhaps a week) to merge.

Sounds good, thanks for letting me know.

Just FYI, I think almost everything is two changes:

• string formatting from "%s" % foo to f"{foo}"
• super(Class, this) to super()

IMO, the useful part of this change is allowing pyupgrade to run on every PR, so it will keep python usage a bit more standard, and a bit more modern. That is my overall pitch for ruff: it will keep the codebase more standard.
