I agree to a certain extent, but I see people regularly using the 4 corner window snapping in Windows. Especially as 1440p and 4k monitors gain adoption.
Fair enough, although I can hear the future complaints about Apple "Sherlocking" Magnet already. :^)
I assume because that type of advanced window management is a poor default for a mainstream audience.
Happily, there are great options for this. My preference right now is Raycast's Window Management extension. https://www.raycast.com/extensions/window-management
