Dear dnsop, I wrote a quick draft to specify that answers returned should be returned in a random order: https://datatracker.ietf.org/doc/draft-kerr-everybodys-shuffling/ This comes out of recent experience we had where a customer saw significant bias in how their servers were used until we

Nick, Thanks. Even if the algorithm is just an encoding format, the same issue applies: It's important that creating new messages with that algorithm must stop well before the receivers stop being able to receive messages in that format. The point of the proposed life cycle model is that doing t
