Similar to black, Refurb is opinionated. There are probably going to be checks which you will ignore. Somewhat of a non-goal with Refurb is bringing to light some of the different ways of writing Python code, and the pathlib module is, IMHO, a very underutilized part of the stdlib.
May I then assume that Refurb is better suited to work on new code? To get back to open(), I don’t know if I would want to go through my company’s legacy code (which runs on Python 3.10) and start replacing battle-tested code everywhere. Same would go for tuple literals over lists in certain circumstances.
I think this will go really well with choosing an „acceptable“ subset of Python for your project, similar to how some companies choose a subset of C++ and then stick with that throughout a project.
I agree that going and updating your company's codebase would probably be a bad idea, considering that there are some kinks here and there. Refurb tries its best, but it is very early on in its development, so errors that are emitted should be taken as suggestions, not gospel.
