I am against adopting this document. It proposes to create a new RRTPYE
that has specialised processing and bundles two problem solutions into
one niche solution that has offline DNSSEC signing issues.

I think it is better to solve the problem in two dinstict parts:

1) Create an ANAME record that instructs where an AUTH server can get updated data
    regarding its A/AAAA records. This can be signed without any problem.

2) Create an EDNS0 option allowing arbitrary query types to be bundled.
    This will allow asking for A+AAAA+ANAME, resulting in getting the
    latest known records plus a reference where to get updates in one query.

There were already drafts out there that address 2)

Also, solving 2) allows bund;ing to be used for other record types as
well (that don't use _prefixes).
