From the article
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.
I just found this thread as well could not be a good thing for us Linux users.

A locked down Windows “gaming OS” is probably what Xbox wants to go towards in some respects. It gives Microsoft the walled garden that they want, can lock out Valve as much as they fancy, and will likely be paired with some new APIs to set back Proton/WINE a few years. Hell, they could even still release XBOX hardware for that niche.
I can definitely see Microsoft releasing a “gaming os” that will lock down your PC and basically make it a console in all but name. I would be surprised if it’s not in the works already for a handheld device.
