I prefer this idea:
mapnik etc could render only objects with version 2 or higher. Not only
does that block out imports, but now we're at the point of completing
various areas, it will make people go back and check them.
<matt amos>But they will just go and make tiny changes to increment the
version without checking</matt amos>
