Replacing certificates can, but doesn't need to, change the public key,
and with this all you are trusting is the public key.
Yes pinned public keys could not and should not be distributed with the
mirrorlist unless you can get promises from the individual https mirrors
that they will not rotate their public keys without sufficient notice.
Again this is going to be generally only useful with a single or small
handful of mirrors that you trust specifically. I wanted this because I
run my own private mirror and connect from untrusted networks sometimes,
some of which will attempt to mitm https connections.
