I really don't know why anyone is worried about advertising AAAA
records for authoritative nameservers.  It just works.  Recursive
nameservers have been dealing with authoritative nameservers having
IPv6 addresses for well over a decade now.  This includes dealing
with them being unreachable.

DNS/UDP is not like HTTP/TCP.  You don't have connect timeouts to
worry about.  Recursive nameservers have much shorter timeouts as
they need to deal with IPv4 nameservers not being reachable.  They
also have to do all this re-trying within 3 or so seconds or else
the stub clients will have timed out.
