It makes more sense to combine the two interfaces, since there wasn't a clear line separating them. The result is a combined interface with just over a dozen methods, half of which need to be implemented by every subclass, while the other half have sensible (and trivial) default implementations and are implemented only by the few subclasses that need non-default behavior.
