Which is why I applaud SPDY as a damn good prototype, which taught us
a lot, for instance that shoving everything into deflate showed that
it matters how big requests are, and that there are significant gains
to be had.

What we should do now is throw the prototype away, and design a
serialization of HTTP which is as if not more efficient than deflate,
and which is less hostile to HTTP routers less prone to DoS
exploitation, and takes less memory footprint (code&data) to implement.
