I can't find that thread, and I only dimly remember it. I checked Cuis, 
the early adopter of this method and I think you're absolutely right 
about it.
There are only 26 implementors of this method and all but one uses simply

fine at the moment, but will fail as soon as overrides have to be added to 
the system.
