I don't think people should really create those entity maps to prevent anyone else from using their map because most people do want other people to play their map and only 1 server with that map would maybe be full 24/7 but imagine the popularity you would have if a lot of servers had the map.
I have never quite finished a CS map, but my Lord of the Rings map is awesome - just don't play LOTR much anymore :-\
