I think it’s interesting because a notch would have a much bigger effect on other OS interfaces compared to the Mac.

On the Mac, there is generally space up there anyway (usually menus on one side, icons on the other). In “full screen” they’ve decided to just black it out unless those same menus/icons are set to remain visible. In normal use, not really taking up important space.

On other desktops though, it would appear to carve a piece out of the background.
