No, because there is no guarantee that the receiver
of this response
can hand it over to the original client.  You're
basically allowing
for the server to mix-n-match where responses go and
assuming that
all endpoints on the receiving end can share/exchange
replies - and
that's not a safe assumption.

btw - ws-polling does provide a way to solve this
since WSA doesn't
solve it natively.  If WSA wanted to take on
this problem I think
it would be a huge improvement and benefit for the
WS community.
IMO, WSA should solve the anon/firewall issue w/o
the need for
additional specs - but I suspect that's out of scope
right now  :-(
