In an ideal world, I agree with you. But if you ever try to make a mass market USB device you will quickly learn that the computers which your customers will connect your device to and the cables which your customers will use will greatly vary in terms of quality and compliance to the specs.

Shonky manufactures wouldn't be able to gain advantage by cutting corners.

The standard EMC tests should be specified using generic cables, connectors, etc.
