HTTPbis isn't a protocol, it's the name of an IETF working group
responsible developing and maintaining HTTP.

What you're referring to is called "Network-Friendly HTTP Upgrade":
http://tools.ietf.org/html/draft-tarreau-httpbis-network-friendly-00

But HTTPbis chose SPDY as a base for HTTP/2.0, so there is no point in
adding support for all the proposed alternatives (even if they are
indeed better).
