Not sure I follow - a Callback is based on the idea that you _do have_ a 
functional interface.

I don't think it makes sense to mix the abstraction levels - the binder 
will represent all callbacks using Callback, so I don't expect a user of 
the high-level binder to mess with SystemABI interface to allocate stubs.
