RFC3205 (BCP56) said some of it a bit earlier, and was ignored. I'd say

RFC3639 was ignored too. For a practical lesson on the same topic, I

a critical study of all the RTCWEB drafts and of draft-ietf-dart-dscp-rtp.
I think they show the depth of the hole we are in.

Just so I don't rudely put words in your mouth, I'd appreciate your
unpacking what you practical lesson you anticipate learning there.
Actually I think my brain was a bit fuzzy when I wrote that, but the point
is that when we start bundling up things that don't naturally belong together,
because we are trying to defeat middleboxes that perform DPI (for traffic
analysis or any other reason) and/or IP header munging, we end up with
artificial complexity that is unlikely to result in reliable, efficient
communication.
An old story, I know. Since before RFC 2775 at least.
