How do we differentiate between a building, deleted in OSM three years
ago, because it was demolished, and one deleted because somebody had
made a mistake, or re-drew it in better detail?
This is the whole problem with 'deleting' anything from OSM data currently. It
is all too easy to simply 'delete' something and then add a new version of the
same thing, loosing all of the history for the existing object which may well
include useful validation data! Import data is one of the offenders here, where
a new 'iteration' of an import may well simply wipe previous data. This is why
we need to close these holes in order to maintain the integrity of data that we
already have!
