They do, and PowerToys also has some additional functionality in FancyZones, but it's still not perfect. It's hard to express "I want exactly this window alongside exactly this other window" purely via the keyboard, it's hard to cycle between multiple layouts, it's hard to launch a new window and have it appear exactly where you want etc. I'm not very interested in VR personally, but I am hopeful in the long term that eye tracking, gestures, and voice control make interacting with computers spatially a lot easier, just with the already-quite-good 2D paradigm we've already got.
