Microsoft has officially announced its intent to move security measures out of the kernel, following the Crowdstrike disaster a few short months ago. The removal of kernel access for security solutions would likely revolutionise running Windows games on the Steam Deck and other Linux systems.

  • Could very well be possible. Apple did the same thing with macOS Catalina in 2019. Since then, there are no kernel extensions, meaning no third-party code running at kernel level. This greatly improves the security of macOS, and other desktop operating systems should do the same.
