I do think you're correct, but one particularly sticky issue is what you do with all the subtle cheats. Rather than developing an exploit with wall-clip, radar, auto-headshots and so on - all obvious to a human moderator - what if you make one that just lowers recoil by a smidgen, 20% or so.
If you're watching the game as a moderator you could never tell that's what's happening. Yet -20% recoil, especially for a competitive esports player, would be such a massive advantage as to make that player the best in the world, but a way that looks quite legitimate.
