Depends who pushes it and how - Steam (Valve) have the clout to if not to "take over gaming" at least turn it into a duopoly on the desktop/laptop from an OS point (from a game client point of view there is already Steam.....and way....over here everyone else).
I don't think anyone else does.
There isn't any technical reasons preventing it, PS5's are based on a heavily modified BSD - it requires a single vendor to standardise and support the platform with enough resources/commitment to do it properly.
Sure valve can make Gamedroid a reality, but Valve seems to be on the side of not using KLA themselves.
And, again, Gamedroid != Linux and PS5's OS is not anything like normal BSD. In both cases (hypothetical Gamderoid and current Console OSes and Windows) the game companies are granted a controlled runtime environment. Linux will not support any effective KLA without a third party providing a blessed (all drivers must be signed, secure boot, etc) distro.
The reasons are:
* PITA to support different distros (although not infeasible).
* Trivial for anyone to just write their own kernel module which your KLA is blind to.
* Trivial to modify how your KLA driver hooks Linux to make it blind to the cheats.
