Interesting, I didn't know such patrolling took place at a country scale in OSM. Have you revert/re-map stats? 

However with your point 1)you have an idea. 
How about a service rendering the area affected by an edit before 'commit'?
This preview could be the place for an additional warning about the the live DB.
