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 
reflect the class hierarchy. The only exception is #ShoutEnabled which is 
fine at the moment, but will fail as soon as overrides have to be added to 
the system.
