Of all the places in Jabber to value backwards compatibility, dialback is arguably the most important. IMO, the real trouble is not the implementation difficulty, but the fact that dialback is underspecified in the RFCs. Let's get this thing fully specified in the bis drafts, and then I agree with Matthias: MUST for receiving and MAY for sending is the most compatible path to take.
Is it necessary to specify the gory details of when-to-send in the bis drafts or would it be sufficient in a XEP? Philipp
