I wonder if anyone at Valve is working on bringing trusted boot into mainstream Linux desktop usage. I'm pretty sure that's the core hurdle that keeps game developer's wary of the anti-cheat situation on Linux.

But it does open the can of worms of making it easy for apps/games to only work on specific Linux systems. We see that with how GrapheneOS has essentially the same verified boot functionality as "normal" Google Android but that doesn't actually mean any apps that want verified boot actual work on GrapheneOS.

Maybe if Valve creates a consortium of Steam verified boot certified distros. Then Valve could require that games that publish on Steam with verified boot requirements have to support any distro in the consortium. That seems like it would likely prevent the issue. The core issue being that you don't want to make it so easy for developers to prevent their game from running on certain devices that they just turn it on just because "why not?". The worry is losing games that might have supported Linux dropping support for all Linux except SteamOS.

We sort of have that now with secure boot in a way. Microsoft makes it so that other OS developers can boot on the vast majority of OEM Windows computers without disabling secure boot.

What are the disadvantages of desktop use variants?

I guess I switch to single boot Fedora Silverblue just in time

As people have said containers is amazing. But in the scenario where you really need 2 completely separate browsers and don't want to use different operating system accounts (I've done this in the past).This extension has worked well for me https://addons.mozilla.org/en-US/firefox/addon/profile-switcher/ It's not ideal that it's an extension but it does do its job
