Yes, but nonetheless, we either get a solution that affects gameplay experience, like enemies popping out with a delay, or that works only partially - in a variant with reduced walls, in 100% of cases, a cheater will have a bit more time to prepare for what's around the corner.

It is true that there is no silver bullet. Anti-cheating solutions are all about compromises. Ring-0 anti-cheats are just another compromise that enable anti-cheat developers to scan for cheats efficiently, with some risk of privacy abuse added (and not as big risk as some may think - I believe Microsoft would revoke driver signatures from any anti-cheat developer that tried doing shady stuff, after which the developer would go bankrupt, most likely). This is not a compromise that most of HN would take, but I don't see a problem if users are well-informed about the risks.

False-positive bans of legitimate players can become a legal liability, especially for users that paid real money for the game.
