Makes sense to me to make that MUST, since that's the entire point of this document.

I would assume that's implied, as BOSH is the only defined transport for the http/https scheme, and I don't expect for us to define another given the existing deployment base.

However, I can see where this could get fuzzy. Any suggestions on a solution?

Yes, this intentionally mirrors the process used in the TCP binding. The Prosody implementation of this spec actually does exactly that 'naïve gateway' approach internally to convert the framed stream to the TCP C2S stream format to reuse its existing code paths.
