I've seen it done with human observations instead of AI, e.g. for validating the skills of the best rhythm game players or the best speedrunners.

My perception (purely from personal gaming experience, to be fair) is that most esports games' existing anti-cheat solutions are good enough at suppressing obvious cheaters, so there's not enough benefit to adopting a system like this for the vast majority of players for the cost.

My understanding of TF2's problem is partially that it's easy to cheat, but unlike other games, it's also easy to cheat on multiple accounts simultaneously on the same machine, and there's not enough (if any?) enforcement to deter people from doing this.
