They allow people to talk about different things that are happening with clarity; right now, people are using the term "HTTP/2.0" very, very sloppily, and that's a concern. "It means what I mean" is not a great basis for communication.

Yes, good point. We're already seeing the effect of this blurriness in terms of what people consider the "framing layer."

To me, EVERYTHING about mapping HTTP-specific semantics is in the "HTTP" section; everything that's generic -- which includes streams and stream management -- is "below" on the framing "layer."

I'm OK if we choose to use "HTTP/2.0 Framing" and stick with it -- it's just that it's used inconsistently now. However, this may not be the best name, because it has "HTTP/2.0" in it, and then we go and talk about using HTTP/2.0 *on* it. OTOH I'm not thrilled about introducing Yet Another Acronym...

Cheers,
