I do think so to be honest and i say that knowing it would be a good bit
more work. You can penalize flowfiles though that are 'not ready' - we might
need to allow penalization values on a per flowfile basis (add an api call for
it i mean). I think it makes a lot more sense to the user and would be more
powerful/configurable.---
