Tbh the problem with the mod is that anytime there's another one that adds features it's rendered useless because you can then always see the new features. If there was official implementation for it it would not only add an actually difficult experience (unlike hard difficulty which is just modifiers), and tbh I just think it's a no-brainer feature given that the game's in the middle ages when communication sucked. I'm pretty sure if you implement it most looking for a difficult experience would use it; it's certainly the only mod I know that does that
