Long ago when we designed the consensus engine, we agreed that it would detect stale event internally. It would be a simple change contained within 1 component. So why use this approach?

Long ago when we designed the consensus engine, we agreed that it would detect stale event internally. It would be a simple change contained within 1 component. So why use this approach?

The problem I keep running into when I try to do this in the consensus engine is that it drastically increases the complexity of that component (adding new inputs, adding new outputs, etc.). In my mind, the overhead of keeping a stand alone hash map of non-ancient self events is justified by the separation of concerns and reduction in complexity of the consensus engine.
