All these games already have an authoritative server. These cheaters aren't breaking the rules of the game by being invincible, super speedy, etc. they're aim-botting and wall hacking. Those cheats can't be prevented with authoritative networking.
why can't we prevent wall hacking by not sending packets of enemy players position if the user can't see them on their screen

I dont know what kind of authoritative server Apex Legend uses that let the infamous "Tufi" hacker do what he did for so long. IMO it should be trivial to ban someone hitting more than 80% of their shots as headshots,, dual weilding weapons that were never supposed to be dual-weilded. Charge rifle beam permanently shooting and swapping armors from miles away
