The discussion on attaching boundaries to physical objects appears on
other local lists and talk@ and dev@ at various times. Lots of
opinions. :-)  And quite some variation in personal mapping styles.

I think combining the boundary deletion with remapping is
not-vandalism.  Cleanup by a local mapper, while attending to the data
is much better than purging by a script, in my opinion.

I'd like to see "somebody" document a quick and easy way to access
official boundary data outside the OSM DB.  Mapnik could display the
boundaries as a layer when desired by the consumer.  Nominatim can
search w.r.t. external sources.  $something is used to make your local
postgis queries do the right thing.

This sounds harder than just putting the boundary data in the OSM DB.
But keeping a local OSM DB up to date also sounded hard until minutely
mapnik and replication diffs were created.  Suddenly it doesn't seem
so hard.
