Who or what decides that the ID 1381574156 should move rather than 
disappear?

If it is to be a computer algorithm, who writes it? What happens when a node 
tagged as a pub turns into a way tagged as the same pub? Maybe it turns into 
a relation (because it is a multipolygon)?

If it is to be a human, who will do it? I agree with Frederik: the mapper 
shouldn't be burdened with dragging a UUID around everywhere. Maybe the 
editor could ask the user "You just deleted this pub. Did you mean to move 
it instead?" The editors will then become enormously more complex than they 
already are.

This sounds a lot like the conversation we're already having elsewhere in 
this thread.
