One problem is that it seems to be the only way to get the FQDN
of the host. FYI, I use the FQDN as a way to identify the hosts
(and a FQDN is more meaningful and probably more stable than an
arbitrary UUID).

But I don't know any software that tries to resolve the FQDN,
except broken MTAs that reject mail if they can't resolve the
FQDN, despite the fact that the client is on a private network.
