   It's very unlikely that there will be another import unless by chance 
there someone has created data that is of greater quality than we would 
typically see in OSM.

   There is some active work on reusing our changes.   So deletions and 
moves can be detected.  If you later create an area polygon for the 
element, copy all the tags from the node to the polygon, then remove the 
node.
