Yes, this is a known challenge with subnet delegation in
MirrorManager. We're trusting package signing (and soon, repodata
signing) to prevent rogue mirrors from issuing unsigned data. In
addition, I'm working on adding in a way to prevent stale mirrors
(with signed content) from being used.
Perhaps it might also be a good idea to add a comment to the default
yum.conf for gpgcheck explaining what a bad idea it is to set to 0. I
could imagine people setting it to 0 not understanding what
they're doing. Especially if they're familiar with gpg's encryption bits,
but not its signing functionality.
