Completely agree about broken protocol. Unfortunately, I doubt their will ever be a real impetus to abandon it; we will just keep muddling along strapping ever more duct tape.

But let's dream, what would your protocol be?

For some reason I have always had a hang up on the headers. The lack of real concrete specs, forging clients, and now the ugly monstrosity of CSP. I love the effect, but in my dream new protocol we have to opt into features during some kind of app / client handshake.
