But again that will only tell you if the window is iconified. If the window is both window state Iconic and map state IsViewable then the window is still required to redraw properly. Even in Ubuntu 18.04 this is necessary to support window previews when you right click on an icon in the dock. I'm not sure if there are any other reasons for it...
