Bulk imports should always be done under a user dedicated for that one purpose. Bulk re-imports should only replace data if it still belongs to the dedicated user. If somebody has edited it, then it belongs to them now, and won't be touched. Then, we should rely on maplint to look at the tags, and mark data which has duplicate import tags (presuming that the user who edited it didn't delete the import tags). Otherwise, the problem devolves to duplicate data entry, which is a problem we need to solve regardless (e.g. Poughkeepsie, NY got mapped, and then overlaid by the TIGER import).
