The proper way to deal with this is to make it easier for OSM-related 
tools to access third party databases, then tell the gov't guys to 
maintain their data in such a "certified OSM compatible third party 
database". Anything that goes into OSM must be changeable by OSM 
mappers. We're not a hosting service for 3rd party data ,-)

I agree that some method of "permalinking" would benefit many. Today we 
have people explicitly linking to relation IDs which is not very 
helpful. It will be difficult to make such permalinks unbreakable 
without restricting editors but worth a thought.
