Why do you exclude the standard library like it's a small thing? If it's not part of the language, why do they host the documentation on the same website and ship it with the same package?
In C, dotnet, Rust or even Javascript, stdlib breakages are basically the same as language breakages. Python is an outlier for this.
Minor breaking changes in the standard-lib are normal in python. They have always been there, and are usually communicated over a long timeframe, so people have enough time to prepare. The point is, they are usually won't affect many people, unlike major breaking changes in the language itself.
The standard library is maintained and delivered by the CPython-team itself, but at the end of the day it's just a better maintained 3rd-party-collection you have to trust over your own code, and it's not much different in that regard than any other 3rd-party python-code on pip.

That might be because C and Javascript have no serious standard-lib. For python it's more comparable to the builtins, what they deliver out of the box.
