"DNS SRV RR" [RFC 2782] also mentions adding SRV RR Target A/AAAA to
the additional section.

# draft-ietf-dnsop-svcb-https also mentions adding SVCB/HTTPS target A/AAAA
# to the additional section.

In 2017, 2018, QDCOUNT>1 or multiple qtypes were discussed in dnsop WG.
At the time, I proposed draft-fujiwara-dnsop-additional-answers-01
and compared 5 proposals.

At the time, all proposals avoided QDCOUNT>1.
