I think stat based bans are the ultimate solution for all the client side bullshit.
If you use statistics, you will sometimes get it wrong, but in the other cases the cheaters are completely out of luck. You could offer the source code to your game willingly and it wouldn't help them very much.
If the cost of a false positive is $50 for the gamer and the chance of it happening is rare, I think many would quickly understand the value proposition from a game experience perspective.
Assuming your false negative rate is low (I.e., you have high classification margins), you can make it extremely undesirable for players to engage in unfair play. Even soft cheating like aiding teammates with streaming and discord side channels could get picked up by these techniques.
