Perhaps - just feel some people abuse this by having one windmill to power their entire base sometimes But, yeh I can see how that would be something difficult to add.
It's not out of difficulty, given FC is a quite experienced coder and designer, so much as it's a rather poor fit for the game. "Realism" aside, which is always used as a justification for a desired feature without admitting the true desires behind it, it adds nothing of value to the game. Hooking up a new power source to each and every mechanical device is prohibitively expensive, and takes up a set amount of space. Meanwhile, by allowing objects to draw mechanical power from only a single source, what becomes important is the way to reach that source. If you've ever tried managing large amounts of gearboxes and axles in an enclosed space... it can be a challenge in its own right. It also allows for the possibility of setting up power lines to other nearby locations, and weighing the cost of building those lines vs. creating a whole new power source.
