Yes, there have been several disputes between editors because of this 
exact scenario.

Also, I often need to keep a disused:shop=* around because the newest 
street-level imagery in an area is from before the shop closed. 
Sometimes mappers can be complacent about street-level imagery being 
fresher or more ground-truthy than aerial imagery, but this is not 
necessarily the case.
