Lots of the things you can do with your Apple equipment aren't supported by Apple. That doesn't, necessarily, mean it will harm your machines, just that Apple don't want people calling their support phones asking for help doing, more or less, weird things with their Apple products, and, of course won't take any responsibility if your "smart" ideas actually managed to hurt the hardware. Apple cannot test and support all possible uses of all their products. They have to stick with "what's intended".
I understand Apple very well.
