It is used to spare drivers that don't want to fully exploit SuperSpeed functionality from handling SupperSpeed descriptors and still be able to operate in a SupperSpeed mode. Please note that the gadget driver can still provide SuperSpeed descriptors with correct (and not default values) if it wishes to. I hope I understood your comment correctly.
