I don't see the appeal of any ultra-realism, but as a bad player who loves games, this would have the same effect as removing my ability to attempt it. Might be wrong, but I strongly prefer the idea of the vast majority of NPCs being dumb and abusable rather than quasi-aware and backed by game mechanics and in-game authority systems. With a change of perspective this could be really interesting and cool, but I wouldn't want to play it.
