I agree that we don't need to make a normative dependency on a header field
definition. My interest in removing this as a normative dependency is
because many people are confused about the HTTP/2 spec explicitly defining
how to do TLS for http:// URIs. Yet, my feeling is that some/many/dunno of
us don't want to block the HTTP/2 spec on this, and want to decouple that.
Therefore, I think we should discuss explicitly decoupling that from what
we're depending on in HTTP/2.
