Personally, I do think you need a non-rewirable 2-pin option like Europlug, but alas, given the ring circuit layout in use in the UK that's highly unlikely to ever come into existence !
A rewireable replacement would also be nice....for when the existing molded-on plugs fail. As they sometimes do (wires and insulation going to the plug sometimes break if it's been abused or accidentally yanked).
