Ah OK. I was confused a little about what makes a component, it isn't just state it is also about lifecycle.
Imagine a "health-check" which polls some service to see if it is there, it needs the service and some ohDear notifier component but it doesn't have any state as such (or at least no state that changes over time), but it does have a notion of start/stopping. This would be a good candidate because it has a lifecycle. Thanks again.
