It'll take a lot of coding to make this work. A LOT of coding. Talk about defining the districts around the map, their borders, tunnels and the undefined areas such as the vents access to the vault. Also in server 2, the districts are very hard to define, so the program that runs this 'auto warn' will mistaken the player breaking NLR when he hasn't.
Also, the development into this program will take a very long time to even get it started, considering the amount of effort needed to do so. Even though the positives are almost equal, the negatives do outweigh. Besides, 1 line of coding could possibly ruin the whole thing and will need to restart.
