So only play multiplayer games for which you know enough people who also want to play that same game and on a schedule that works for you?
If that's the tradeoff, then yes. I don't know. I keep a Windows partition for Fortnite to play with one of my friends, and I miss the days of CS:S with 64 player zombie mod.
I don't know if enabling KLAC in Linux can happen without opening nasty doors for other software. If it existed, perhaps one could have different kernels to boot into: One for the invasive software that one boots into for gaming and a secure kernel for normal work, perhaps even with different userspaces.
Although impractical, wouldn't that be nicer?
