Imagery is only out of date if something was (de)constructed since the
imagery was collected that would affect how that area is accurately
mapped. Therefore to me it makes more sense to tag the newer objects
rather than entire areas with a specific tag that editors would pick
up and act upon appropriately (highlight, emit a warning when you
change geometry or delete it, something like that)
