Yes, that would be nice!

Good points.  Another option would be to scan both.  At least our
resolveall.nse could be agumented to do so.  Though I think that
functionality would be welcome as an official Nmap option at some
point.  Resolveall.nse is great, but it requires a pretty awkward
syntax (--script=resolveall
--script-args=newtargets,resolveall.hosts={<host1>, ...}) compared to
a plain Nmap option.
