Except when they find a way mirroring the Mac's desktop in this environment on a nice way. Straight up 'external display' mode (more like external 3D space), but with less constraints on how to position the windows and the taskbar ... and consequently more trouble on navigating among those. Desktop icons might be a burden too, also wonder what to do with fullscreen mode.
Anyway, if one app was used on its OS for mirroring the Mac environment on a nice way, that could be enough for me.
I feel that this feature looks more like Continuity than real desktop/app mirroring. You'll likely have to have a corresponding app installed on the device to run it this way.
