The thing about minecraft, is npcs can go through eachother, for instance, you can put 1000 villager npcs in 2 blocks, in real-life however, you couldnt fit 1000 humans into a tiny room. The formations just wouldnt work since this is a mod for a game. Advance/retreat horn is something that is needed though.
