> I agree that having some first-party or reputable anti-cheat driver or system, is probably preferable than having different studios roll out their own anticheat drivers. (I am aware there are studio-level or common third party common anti-cheat solutions already, such as Denuvo or Vanguard. But I would prefer something better)

Only Apple really has enough platform lockdown to achieve that. Whatever Microsoft ships would have more holes than swiss cheese (not that I'm opposed to that or anything).
