It's funny, because as a MacOS user I pretty much never use multiple desktops, although I used it a lot in GNOME 2, because of how obvious it was that there was something in another desktop[1]. I think it really help multiple desktops feel more "grounded in space", like another monitor.

In MacOS, other desktops feel like a background thing that it's easy to forget (kind of like having a process running on another `screen` session).
