This is the kind of architectural view that sounds absolutely wonderful,
but it can get sub-optimal when actually enforced.  For example, if we end
up recreating all of HTTP as a set of SOAP headers, then we have
duplicated the protocol stack, and we'll actually hurt adoption -- HTTP
users wanting to send SOAP messages in a simple request/reply mode will
not want to deal with ReplyTo, since an HTTP post guarantees a response
comes back.  Similarly, looking at WS-Management, there's lots of things
being created (oh sorry, "leveraged") to re-create SNMP:  SOAP over UDP,
WS-Enumeration, Ws-Events (aka SOAP-Traps) and so on.

Layering and abstractions are great, but so is "optimize the common case."
After all, we want to end up like the IETF protocol suite, not the ISO
