It is my view that IF binding.sca is not present on
the service, THEN
the wire from the client MUST use binding.xyz.  So
this is what I think 
happens for both my proposal and Dave's variation.

No, tough, the configuration says that the wire MUST
use binding.xyz. This
is not allowed.

There IS a way of getting behaviour B) - the service
should be declared 
explicitly with both binding.xyz AND binding.sca.
