As I was happily asleep for this conversation...

I have no qualms with the other items, but I have some questions about this.

Did the discussion address questions of functional difference between this design and the HTTP/3-based design?  The way that this works is subtly different in ways that are not limited to just the unavoidable differences (that is, reliability and ordered delivery).  To a large extent this is grounded in attempting to use HTTP/2 stream creation mechanics.

I'm opposed to adoption of this document.  I don't believe that it can be made so due to some fundamental differences in how HTTP/2 and QUIC stream states.

If this problem was acknowledged, then I have every confidence that the people listed as authors are able to find a solution.  But generally adoption is about the document more than the people.  Adoption means agreeing that the document contains approximately the right shape for a solution.  I can't agree with that in this case.
