Djk,
With respect to the non-compatibility angle.
We do have plug/socket configurations here that use either, 2 round (Phase+Neutral) pins or a single round Earth pin to complement the standard flat pins.
But I agree Dave, we didn't always have them configurations either, but that's another thread in itself!.
