fedoraproject.org can't be a CNAME because it has other records like
MX, NS, SOA, etc.  We'd have to switch to using
'www.fedoraproject.org' which could be a CNAME into an unsigned
subzone.

But then you'd still have the problem of relying on an unsigned zone
serving up DNS data, eventually no one is going to trust it.
