It's hard to know.  No application written using BFG can use the IFoo() pattern 
at all, and no one complained.  The only generalization I can take away from 
that is that anyone who has written a BFG app and also used the ZCA APIs did 
not care about the IFoo() pattern.  That's maybe not a really useful 
generalization, because many BFG apps don't use the ZCA APIs at all.
