Actually "same channel" is mentioned in the WSDL Message Patterns Draft 
only in the context of request-response (where it makes sense). That is 
a means of correlation, but it is generally N/A for asynchronous 
interactions.

Are you saying that the WSD group has decided not to touch that area at all (which could explain dropping the Request-Response MEP in favor of just In-Out)?

On the other hand, if that group does not address it, other groups will, as you say (in addition to the ones you mention, BPEL has also its own way of dealing with it). The problem is, as usual, that those groups might introduce different concepts and mechanisms that, in the end, will not easily interoperate.
