This means that any side of the orElse can redefine the whole Behavior—the idea behind the And/Or combinators was to move towards an encoding of hierarchical state machines where the pieces progress independently of each other. Without this independence there cannot be decoupling of the combined pieces, which means that this construct does not implement compositionality in full.
An orElse method may make sense on partial Behaviors nevertheless, for pure code organization reasons. What do others think?
