I will note that NO ONE has EVER explained to me how this is more
insecure if you are canonicalizing DNS names ... which everyone does.

   This is not an exploit of the Kerberos protocol but of the Kerberos
   trust model.  The same can be done to any application that must
   resolve the hostname in order to determine which domain a non-FQDN
   belongs to.

I suppose I can see a case where you're getting stuff out of
CellServDB; those names are already FQDNs.  But if you're looking up
your AFS cell information via AFSDB records, then you're already in the
same boat.
