>A very naïve person would expect that changing where the keycaps are would change which switch corresponds to which keycode.

I don't agree with this. Nobody would expect that rearranging the buttons on their car dashboard would change the original functionality. Same for buttons in a lift, coffee machine, anything you care to name. People are very familiar with the idea that the switch is just a sticker on an underlying mechanism. They don't think the letters inscribed on the plastic magically embody some functionality. So I think your whole premise is wrong.
