I don't think you can drop section 3.4 completely, but it should be updated
to acknowledge Refuse-Any
<https://tools.ietf.org/html/draft-ietf-dnsop-refuse-any-04#section-4>.
Only behavior 2 (HINFO synthesization) allows total ignorance of special
ALIAS behavior; every other (including conventional) needs modification to
deal with ANY queries against names at which ALIAS is the only RRSet.
