There have been many breaking changes throughout python 3.x releases:

- standard library modules removed

- zip error handling behaves differently

- changes to collections module

- new reserved keywords (async, await, etc.)

You can argue how big of a deal it is or isn't, but there were definitely breakages that violate semantic versioning

Python doesn't follow SemVer, that's why.

Clearly, which is what I was showing. A poor design decision imo

[eigenspace]

They removed entire standard library modules? Wut.

Yes, e.g. https://peps.python.org/pep-0594/
