Having done this for my L1 visa, and jettisoned the USB key I forgot was on my key ring, I'm still puzzled by the author. All the documentation is very upfront about this procedure. I think it should be obvious to anyone vaguely technical the range of small bugs that can be made now. As such removing disambiguation is pretty sensible plan. Rather than airport security which makes a pretense of banning "dangerous" items at least in this case they can say you were warned and there is no room for misinterpretation.
