I actually prefer that they don't build it in. I just wish that the APIs for working with windows were a bit more robust so we could get better performance out of applications that do something less trivial than moving a window to the left side of the screen. Things like Amethyst and Yabai are really slow, especially when you compare it against auto tiling wms in linux. I don't even want auto tiling, I just want a more performant way to perform window movements and to query the state of the space so you can swap windows around or move directionally between windows on the screen. When the OS starts creating new shortcuts that cannot be altered, it becomes a headache. I'd point out the majority of Windows' winkey shortcuts, like one to activate the gaming menu or to bug you about microsoft office as examples. No operating system has a complete, sane stack when it comes to dealing with window management, but I do appreciate that the choice for window management apps in MacOS is extensive and diverse.
