Or maybe should I do this in this PR as well?

It would be best to do a PR to extract them first, than we can back merge it into this PR which would make it a lot easier to review since it would minimize the amount of code changes

I noticed a few things that the linter wasn't picking up when doing the review so I turned on some more rules that would catch these automatically as its likely easier than having to wait for me to review.

I think this is ready to go once the issues ruff has found are addressed.

I think this should be good to go
