I use walkways a lot, especially to climb cliffs. I have noticed that some people have asked for conveyors to be connected to walkways (great idea) but I don't think anyone has asked for power connections to angled walkways (it is possible to attach to level ones). Dragging all the equipment and fuel you need for a fuel generator up a cliff face to power a radar tower is a pain. Getting minerals down from on top of a cliff is also daunting.
