It actually surprises me given Apple is very pro accessibility. The reduce motion option is after all an accessibility feature. It is always why I never understood why Apple don't embrace more keyboard shortcuts for simpler app window management (snapping) rather than the decade old, half assed implementation we have currently.
For me macOS would be perfect with just a few very small features for better window management built in along with the ability to customise it a bit.
I'm not talking full on tiling window manager level features with gaps, master-stack, fib spiral, etc. Basically just something like Magnet/Rectangle built into the OS out of the box, plus two-window resizing (like we already have with the current full screen snapping feature).
