You forget one very important item: * Somehow get all manufacturers to only create quality cables complying with the standard whose capabilities match what they say they do. That won’t happen. Some manufacturer will start making a cable that’s longer than what the spec says is possible, or will try to get away with a bit less shielding or a bit less conductor in the cables than what the spec requires, or will decrease quality control, so that their cables are fine, on average, but 1:1000 buyers will get a melon that’s sub-spec.
