I thought of a compromise: add the number of times a notification was generated (coalesced count+1) to the callback data. That would satisfy any backwards compatibility concerns and my use case too!
If you are suggesting that the server poke data into the notifier's opaque payload, I vote no. Maybe the NOTIFY command can include a switch to enable this behavior. No syntax suggestions at this point.
