People in the Python ecosystem have come up with plenty of new things over the years - eggs, wheels, conda, poetry... Coming up with something new is the easy bit. Getting everyone to agree that a new thing is better and stop using/recommending other things is much harder - almost impossible, if those other things serve some use cases fairly well.

The fragmented ecosystem is one of the main complaints about Python packaging today. And that's really tricky, because the main way the open source world knows to solve problems is to create new tools, and that doesn't help when the problem is 'too many tools'.
