Please note that I'm not familiar with KiCad code, but I fail to see how this could possibly work (other than introducing an unnecessarily complicated workflow). This might work well for art where you draw some nice graphic of an animal, and you only decide how big the graphic should be when you export it/save it/print it. When you instead load a component footprint, you need to know its exact dimensions. Let's say that a courtyard should for example be precisely 1 mm = 1,000,000 nm wide. If you suddenly decide that you need a PCB that is 7.5 m wide instead of 5 m, so that a unit is 1.5 nm instead of 1 nm ... what do you do? Do you just end up with all your components being 1.5 mm wide and with the wrong pitch? Or do you keep transforming the coordinates every time you change your mind about how big your scaling factor should be? Should the courtyard then shrink to 1,000,000 / 1.5 = 666,667 units (and you basically end up with something way worse than floating point numbers)?
