   This is a good example where multipolygons make sense.   I have run 
into this in the past and naturally migrated to a multipolygon instead 
of clicking through hundreds of nodes.

   However for smaller landuse areas such as residential neighborhoods 
or shopping centers, there may be only 4-20 nodes per adjacent polygon. 
  For those cases, I find that multipolygons only increase the load on 
future maintenance and present a major confusion factor for new users.
