These are QA'd:
Other [prefix] Python [suffix] distributions are not officially QA'd by the
core Python team.

These are the PSF releases: https://www.python.org/downloads/
There are many redistributions with various patches applied.

There's really a "ship of theseus" argument: it is defacto standard
practice for downstream distributions to distribute modified copies of
Python while retaining the name Python. How extensive those patches are is
likely irrelevant to a trademark dispute (of which there is none here).
IIUC, when a developer forks (e.g. clicks "fork" w/
github.com/python/cpython), there is still no need to change the repository
