Why would it be a problem for demuxers?

* HTTP is stateless.
* Messages are self-descriptive.
* Annd RFC 7540 section says:
All HTTP/2 requests MUST include exactly one valid value for the
:method, :scheme, and :path pseudo-header fields
... with :authority being mandatory except in certain edge cases where
there is no domain:port applicable to the message.

Thus HTTP/2 messages contain all parts of an absolute-URI in their
pseudo-headers. There is intentionally zero ambiguity now about what the
message means. Gone is the HTTP/1 scheme == transport protocol type linkage.
