 This is basically the same as additional processing for NS, but about the
 case we are returning an authoritative answer with the zone's NS and
 A/AAAA RRs for the NS names (e.g., when we serve example.com, and are
 returing www.example.com/A in the answer section, example.com/NS in the
 authority section, and ns.example.com/A-and-AAAA in the additional
 section).  There's a subtle point in this case though: whether we should
 include A/AAAA RRs under a zone cut (consider the case similar to the
 above example but the NS name is ns.child.example.com, and
 chilld.example.com is a zone cut).  BIND 9 excludes under-cut RRs; NSD
 include them.  What should we do?  Note that if we want to optimize the
 additional section processing we may want to do the same thing as NSD.
