I agree, pathlib is really powerful, and I can see myself using it for new developments.

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.
