I do a similar thing in my DNS crudware, a pseudo-entry in the zone,
every time the background update script runs, it does A and AAAA
lookups and puts the results in the real zone, bumping the SOA serial
if the result changed since last time. It's a crock, but one that we
all seem to want.
I suppose we could invent something like an AAAAANAME (that's A and
AAAA name), that worked like a restricted CNAME and does an indirect
lookup only for A or AAAA requests. Or overimplement it with a bitmap
of the RR types to indirect for.
