They appear to be talking about CPython implementations, taking into account when those versions continue to be sorted (in the sense of security updates). That's irrelevant for PyPy, which clearly supports version numbers on a different schedule.

It's not irrelevant, because if SPEC 0 says that a particular Python version is no longer supported, then libraries that follow it won't avoid language or standard library features that that version doesn't have. And then those libraries won't work in the corresponding PyPy version. If there isn't a newer PyPy version to upgrade to, then they won't work in PyPy at all.

You might make a different decision if you were targeting PyPy.
