there's no "legacy IPv6" but a lot of EDNS0-unaware ("legacy") mostly
IPv4 based clients, which have to deal with what fits into 512 bytes.

1886bis, currently in "AUTH48" state, instead modified all additional
section processing from "add A" to "add A and AAAA".

I agree that the currently installed base of IPv6 hosts could be required
to change, but I'm not concerned about those anyway.

Exactly. Most of these queries are for a single nameserver's name, which
only has A but no AAAA and even less A6.
