Anti-cheat for Java

There are an incredible number of cheaters when playing PvP game modes, and we need an anti-cheat system. Servers are now in charge of banning cheaters, but it does not work to the degree it should. I believe it would be better if Mojang introduced an anti-cheat that server owners could customize in order to fit the server's needs. This would decrease the number of cheaters while not removing the modding aspect of the game, as you should have an option to turn it off on your own server.
