pytest's setup.py file is there for legacy purposes and is no longer necessary, see: https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html. I believe the only reason to keep it keep direct setup.py install invocations and such working. I don't know if there are still places out there who do this, but pytest 8.0 seems like a good time to stop supporting it. So I propose doing that.
