If they are using PyPI, the project should be specifying which versions it supports in either setup.cfg or setup.py[1].
For example, I decided to only support Python3 going forward. I've had person once open a PR to add python2 support, but I politely declined[2]. As such, PyPI shows that only 3.5+ is supported[3].
