Hey, thanks for this one! I support the attempt to define a record
type that would cover the existing vendor-specific types that
synthesize A/AAAA records in zone apex. If this gets adopted by the
vendors, it means possible zone transfers between these providers. On
the other hand, I don't like the part which moves ANAME processing to
resolvers. I'll comment on that separately.

Besides that, The Security Section should warn DNS operators that
ANAME may be misused to leak data from any internal networks the
server is part of. This was so far concern for resolvers, but with
ANAME it may become a concern for authoritative servers as well.
