I've re-read the discussion in https://github.com/quicwg/datagram/issues/6,
and now better understand the points of view that resulted in the lack of
datagram multiplexing in this specification (I was following that
discussion when it was happening, but hindsight during re-reading helped a
lot!)

I especially appreciate the addition of the text in
https://www.ietf.org/archive/id/draft-ietf-quic-datagram-04.html#name-multiplexing-datagrams
.

I accept the wisdom of getting more experience with various people using
application-defined multiplexing in various ways before adding any flavor
of multiplexing at the transport layer, and agree that holding this
specification up while that experience is gathered, would not be The Right
Thing To Do.

I'm aware of at least two "RTP over QUIC" proposals that assume that
they'll need to multiplex datagrams, so I won't be surprised if we return
to this question in the future, but for now, the chairs are Doing The Right
Thing, and I support requesting publication of -04 (modulo any changes that
pop up in WGLC, of course).

Best,

Spencer
