> Not that it needs saying again, but I'm still in favour of doing something like what Christian is suggesting, or like I suggested earlier (have os.urandom remain good, have Python internally fall back to weaker seeds for random and SipHash if it's run so early that the system hasn't started up fully yet).

It looks like people don't read what I'm writing :-( You are just
repeating the title of this issue :-) (So yes, I agree with you, since
I'm proposing the same thing.)
