Couple of points:

- While request/response may be supported on various transports,
  how it is done by each and how the end-application writer
  then needs to interact with the SOAP sender/node can still vary.

- Whether or not an end-application writer can write in
  "blissfull ignorance of which underlying protocol is being
  used" is an implementation choice and I believe is outside
  the scope of the working group.  (even though of course its
  a nice idea  8-)

This is where we disagree. The application programmer shouldn't care
what the underlying protocol is, only that it supports the semantics
required by the application. e.g. if the application only requires a
request-response message exchange pattern then it would work over any
binding that supports request-response. Why tie it to HTTP only ?
