Human naming has nothing to do with software naming which seems obvious but apparently not. Python package creators should check the pypi registry for names and generally avoid name collisions where reasonable. Common sense applies for reduced confusion for users globally and also for potential legal issues if any party trademarks their software name. What makes one pyx more real than the other is one was first and took the spot on pypi. Simple as that. https://pypi.org/project/PyX/
That's barely 3 years...? I just released an update for a project I maintain that had had a 4 year gap between releases, but is still heavily used by a lot of people. I dread to think that we live in a world where software has arbitrary expiry dates...?
Some software just needs fewer updates. The actual repo had a few commits last year and even more the year before that.
