No, I agree that HTTP doesn't make things easier on HTTP routers. Variable length headers that have to be parsed does nothing for speed.

However, this is the method that HTTP has defined for version upgrades, so if you want to muck around with the first line, you lose the ability to co-exist with HTTP/1.1 on the same port.

And I really doubt that they'll want to switch ports for HTTP/2.0.

One possible method would be forcing width padding of the request-path and Host headers. This would potentially make it possible to use fixed offsets. But this strikes me as inelegant.
