We suggested exactly that a few weeks ago, but didn't get much response (see draft RFC in [2]).

You're right. It's really similar, but suggesting T-E out loud is liking saying Voldemort around here :)

BTW, in another thread Mark said: "As Chair, I get very concerned when people try to make HTTP/2 a trojan horse for "improving" a particular situation, because the experience with new features layered into HTTP/1.1 this way (e.g., expect/continue, pipelining) was poor, and also because we'll be on a slippery slope to having lots of other people throw in their hobby features too."

Why should implicit C-E get an exception?

We've got some ideas for fixing http performance and interop too :)
e.g. end-to-end Message-Encoding [2]; unambiguous range requests (w.r.t. content coding); etc.
