So, implements Stoppable rather than do what the likes of AuthUtil does where it does createDummyStoppable and then has an internal do-nothing Stoppable? Makes sense.

Perhaps add comment that it is a do-nothing stop required by ScheduledChore impls. s/isStopped/stopped/

Maybe in the future we can put a default empty implementation on the interface, and then implementers who don't need it can ignore it.

Maybe we could just use a ScheduledExecutorService at client side, the ChoreService is designed to be used at server side I believe. Anyway, not a blocker for now.
