Given the problems with changing the protocol it does seem like generalizing away from "connection id" to "arbitrary payload" would be useful. Like, add a new "attachment map" area where any application-aware node that encounters the message can attach data. If some node further downstream sends a response message the contents of the attachment map would be sent back as-is. The advantage of "connection id" is that the messages are still of fixed size whereas the more flexible arrangement would necessitate that message sizes vary. In return middleware gets a place to store session information that can be used more broadly than a simple externally generated connection id.
