It depends on the threat model - whose definition is key to any security
discussion.

I'd say that providing the CA certificate of the CA, and to use https
for downloading, should be enough.

Alternatively, if the threat is that somebody may have hacked PyPI,
then hard-code the hash (SHA-3 if you are paranoid) in the Python
distribution, and rely on downloading a specific version from PyPI.

OTOH, I'm -1 on removing the code from Python in a way that it may
come back through downloading. Instead, it is much easier to keep
it included.
