we may have GHz bandwidth drivers, but that doesn't solve the issue of
frequency dependent propagation through a cable. At lowish frequencies
(<100 MHz) I'd suspect that the difference is more one of amplitude than
phase, but still, it's something that has to be dealt with.
One could just have a narrow band filter at the receiving end to pick up
only the fundamental, but then, why not just send only the fundamental.
