I think at the end people would just revert to the old official controller bypass. You essentially just need a broken controller and use its with token, but the control input signal still comes from the adapter.
I think it's a bit late for that. With the advance of AI processing video input, it really doesn't take much to cheat with a 2nd PC/raspberry etc, and feed the adjusted input back to controls. If you search around in youtube you will see anti-cheat only deter the less determined cheater or who don't want to invest in gears to cheat.
IMO, the best anti-cheat is using game mechanism, not by preventing things from happening.
