Why? It's restricted to one display, but will insist on moving from one to another if you make some moves with your cursor. You can't decouple multiple windows of the same app. IIRC it insists on disappearing if you are in fullscreen on another display. It also wastes more space than other taskbars to be usefull and look decent. (disclaimer: I dislike MacOS globally)
