Paul, you are sure you talk about RFC4690 and not RFC5507? Being one of the editors of RFC5507 (and 4690!) let me emphasize what Andrew wrote here. Yes, maybe people have conflated and simplified what we wrote, but the RFC is actually trying to be very very careful with wording and it would be said if text that once was very specific once again end up being watered down. The key message in RFC5507 is that one should minimize the RRSet size, and think carefully if the selection criteria between RR is in the RRType or owner. Patrik
