If there is an HTTP binding then I think it has to follow the Web's
rules of how to use HTTP. The W3C cannot produce recommendations and
findings that disagree with each other.

I agree with you that there is a tension between SOAP being a good
player on top of HTTP and SOAP being "transport agnostic." If I were
more involved in SOAP I would strongly argue that SOAP should choose one
or the other because doing both creates an increasingly
difficult-to-understand specification. But years ago it was decided to
do both. I don't think that that is going to change now.

I'll go further and say that I think that there is a tension between
being a *web* protocol and being transport agnostic. Web protocols will
naturally put URIs at the center of their design. That's tricky to do
running over protocols that have no notion of URI.
