Really you just need to bring detected servers back. That left people with a community that they tended to police themselves because they owned it. But those community run servers meant they couldn't control/shutdown old multiplayer games at will so they got rid of those. Then they started whining that they needed ever more draconian tools to police the online games that they needed to have 100% ownership of so badly.

Although impractical, wouldn't that be nicer?

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.
