The file https://www.python.org/static/files/pubkeys.txt contains some bogus GPG keys with 32-bit key IDs identical to actual release manager key IDs. (see below) I imagine these slipped in by accident and may have been created by someone trying to make a point. (see also: https://evil32.com/)

This is obviously not a serious security concern, but it would be a better look if the file contained only the real keys, and if https://www.python.org/downloads/ listed fingerprints.

These are the obvious fake keys included:
