I don't understand. Wiring environment with old sun gizmo required exactly the same amount of steps and effort. Only difference was that you had to wire Rotation [deg] spinner parameter to U offset of the map, instead of Z rotation of the target. And rotating sun was then done by Rotation [deg] parameter, where as now is done by rotating target in Z axis. I just tried it with older build to be sure, and it's not slower, nor faster to accomplish.
