Hi,

does this need to be clarified before the draft can be adopted or
is this something that can be worked on after adoption of the draft?

We do have a flow identifier to demuxing and we have initial wording on mixing real-time and possibly non-real-time data especially concerning congestion control.  Likely not all will be handled by the doc since, at some point, we get into too many application specifics.  But the basic mechanisms will be in place.

This is something to be looked at closer.  The discussion with David showed that it is non-trivial to get the ALPN allocations and all the implications right.
