Only if you're locked into thinking about HTTP and client/server models.

In a pub/sub world, an out-only pattern (or any out-initial pattern) is a
nice fit, and we expect to see these widely used.  This is because, in
pub/sub, the service is talking, not listening; publishing, not serving. 
The other nodes interacting with the service are not requesters/clients,
but listeners/subscribers.

Because the WSDL is always from the point of view of the service.  This is
ground we have gone over multiple times.
