I think Stage Manager shows their hand—that they think users should manage this with the mouse, with no window-snapping. All this said, I would like to see the full-screen mode get support for three windows, along with a way to stack vertically. There are times when you need more than two windows on a screen. I also think it’s as simple (and stupid) as Apple wanting to continue to use rounded corners and window-snapping not really making rounded corners look particularly elegant.
