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.
