That would make libgnutls indispensable, and would also require us
getting the cert-verification working correctly.
Nothing significantly more troublesome than requiring users to have GPG
installed and have the ELPA key in the keyring.
And of course we'd need to make sure the "fallback to no checking"
works when gnutls/gpg is not available.

Right.

Presumably, yes.

Of course, there are also hypothetical situations, such as someone
setting up a mirror.
