Interestingly, several other lists were copied to this email but not the main httpstreaming list. I would recommend dropping other lists. One comment inline.

If the network will not respect to these code points (which is the case in the open Internet), this won’t help but the servers themselves can prioritize anything they want to in their scheduling or processing. But, I am having difficulty in understanding why this is relevant to a standardization work. It looks to me as a product feature differentiation.
