The crux of the issue is that if you have a circuit capable of
supplying a current significantly in excess of the rating of the
appliance flex, then you need a overcurrent protected plug. So its not
really anything to do with the circuit being a ring or not, even if
that is the most commonly encountered 32A circuit in the UK.

I agree, but most of the world doesn't have fused plugs. So is there a
major problem with, say, those 3A flexes running to laptop power bricks,
plugged into a radial circuit limited to (say) 16A??
