I think the main concern is that res_query is non-standard, but when
it is not available, disabling gpgkeys_dns seem like a simple
solution. Fortunately there seem to already be code in gpg that have
the same issue, so much can be reused.

Perhaps gpg could support it for those keyserver protocols were it is
easy to support that model. Could be a nice test of PGP revocation
certs using CERT. On the other hand, there are some advantages in
creating a new DNS type for OpenPGP revocation certs, that is separate
from CERT. (Query simon.josefsson.org IN CERT to see why... The PKIX
certificate would still overflow the UDP limit.) However,
implementing the idea in gpg might be a first step in dispersing
knowledge about the idea...
