This makes the stakes for getting caught cheating, much higher. It does nothing to "solve" cheating. If someone is using additional code to gain an un-fair advantage, knowing who they are does nothing to detect this.
It's relatively easy to catch cheaters. There's constant banwaves in Valorant, CS2, and Rainbow Six Siege. The challenge is that cheat authors fix their exploits to be undetectable, and the cheaters get a new account in a week or two. This means detecting cheats does not have a lasting impact on cheating's presence in a game. The prevalence of cheating is the problem a game developer is trying to solve.
But it does lower the amount of cheaters as the consequences are bigger. Also makes manual banning/moderation much more cost effective as the bans actually stick.
At the end of the day the goal isn't 0 cheaters but having few enough that the chance of your match being ruined by one is 1 or 2% instead of 10 or 20%
