Not the same thing. Focus doesn't prevent the OS from generating windows or alerts on top of your display content.

  You're not typically cloning your main screen but rather outputting to a second display (that doesn't have the focus). It would be very weird indeed for a notification to wind up on that display.

    Weird but not impossible. The whole point here is that professionals who can't take that chance have always had to use a hardware I/O device because there is no other option.

      Perhaps professionals with a lot of money riding on it, sure. But for prosumers, the status quo was good enough that breaking it cannot be justified by "oh it wasn't perfect so who cares?"

        That wasn't the status quo. The OS has always been able to display things on top of full-screen apps and apps cannot change that.
