You can't create a Python library without a setup.py file. Some of the things that I develop are Python libraries, so, having a setup.py file is a must. It would seem that you aren't developing the same types of things as I am - which is totally fine. But, I've been trying to describe my particular use cases, and for those use cases, the Python tooling isn't great. My use cases aren't that niche, and, they aren't invalid. They are different than yours, but, that doesn't mean that I'm not keeping it as simple as I can.
