I've explained this in Barcelona: it's duplication of code. We need to
define the virtual function supported for each interface that requires
it. The function for each supported function is the same. So why not
generalize it? That's what this is for! Besides, I want to automate this
supported()-checking during the cast, and then a generic macro is
useful. The lot of extra code will end up in the specific interfaces

I need this. I want this. You don't have to use it in your interfaces if
you don't want to. I do.
