I guess I can believe things don't get worse but I still don't know how
this makes things better.  With the current code the request is lost
because it goes to the wrong SM; with the new code the request is failed
by the SA layer.  So in both cases the consumer just has to try again.

So is there some practical benefit we see by adding this code?
