Why not? They are basically the ones that are breaking the
resolution. The DNS is a co-operative effort. Everyone
needs to do their part.

There is NO nameserver that can resolve everything fine.
Named is IPv4 and IPv6 transport aware so it sees
misconfigurations that IPv4 only nameservers don't usually
see because it asks for both A and AAAA address. The later
are not usually satisfied by glue and as such named sees
the zone content and hence the configuration errors.
