That's about as meaningful as saying copper phone lines were never designed for broadband.
That is very true. However copper phone lines are a balanced pair and matched pretty well to the equipment on the other end so interference is not a problem. The mains wiring is unbalanced, unmatched, and has a discontinuity at every socket on the ring and when fed with wideband RF the whole house becomes a transmitter.
