Sadly, with GitHub being a similar case, I think it will take until the heat death of the universe before these services start supporting ipv6.

Well, if you compare it to the state of the Play Store, likely 95% of games wouldn't be allowed to be published on Steam anyway because they don't allow advertisement in games (unless it's for games on Steam itself) and other dark patterns these apps deploy.

I use Secure Boot on all my machines but I just use my own keys with Foxboron's wonderful sbctl utility instead of the hacky shim/MOK method most distributions use.

+1 for uBlue. I did the same for my mother on her laptop and desktop PC for office work. Chose Aurora in this case. Setting system and flatpak updates to automatic means I hopefully never have to look after these systems again as the distro maintainers basically do the maintenance. Setting up Secure Boot with the shim/MOK method and TPM auto-unlocking for full disk encryption using the ujust scripts is a breeze as well.

What actually exists but what I have yet to see implemented in any game I play are those server-side "AI anti-cheat" solutions like from anybrain that basically just analyse the players behavior to fit certain criteria. According to areweanticheatyet.com though there are four games using it already (the most well-known one probably being Lost Ark). In theory ai models can be very efficient and accurate at this (we are not talking about transformer models here like with the current llm craze) but that all depends on how they train a model and what the training data looks like.
