This is missing the point. They were asking why not to use SHA512. The
answer is that the hash does not provide any extra security. GPG is
separate: even if there was no GPG signature, SHA512 would still not
provide any extra security. That's why I said "more to the point". :P
Nobody "must" verify the GPG signatures. TLS doesn't protect against
everything, but neither does GPG. A naive user might just download a public
GPG key from a compromised python.org and use it to verify the compromised
release, see everything is "OK", and still be hosed.
