You shouldn't take that shortcut over the lawn either. There are two answers to that very basic design problem: 1. Build higher fences to force people to walk along the prescribed path. This is often met with resentment, and various attempts at climbing the fence, or even cutting it down. 2. Lay bricks along the new organic path, so that it's safer to traverse. I like the latter choice. The principle is just about the same in the digital world.
