I think there was already a thread on this topic recently on this list
("Order of CNAME and A in Authoritative Reply" from August 2015). There
was some discussion over "adding" versus "appending" and it was pointed
out that a lot of existing code (e.g., the BSD stub resolver) was
written using the "add at the end" meaning.
