Any plan for supporting UML state machine?

Currently there are no plans to change the API in any significant way. Is this something that can be added on top of this implementation? Maybe a new type HierarchicalFSM could be added that utilizes FSM under the covers? I’m not too familiar with hierarchical state machines, so forgive any lack of understanding.
