Having had a look to see what this is about, then firstly I agree with Mark's comments here, but additionally I don't quite understand why a new RRType is needed rather than expanding on the work already done in RFC 9641.
It would seem to me that a DNS client needing to know information about a DNS server would need to use the SVCB record, so it feels intuitively as if the additional information here would be better placed in the same record, eliminating the need for two different queries.
Happy (and eager) to be corrected, of course.
Dave.

As an additional note why is putting the answer into the authority
section needed at all? Just look for AA=1 in the response. Recursive
responses have AA=0. The resolver is supposed to be authoritative for
the name and the RRset.
Additionally if you don’t want a recursive response, don’t ask for one.
Set RD=0 in the request.
