I tend to agree with this, although I think it highlights an underlying 
requirement upon bindings to be able to differentiate between the 
operations. I.e., it should be possible to configure the binding so 
that you can disambiguate the operation being called (e.g., with a 
per-operation URI path segment or query parameter).
