I'm talking about the non-corded variants. Carrying an extra metre of cable around just to get the grounding prong is not great.

As another poster mentioned, it's particularly annoying because Apple does ship the UK adapter in 3-pin grounded form

YMMV. I throw away the non-corded variants because they rarely fit in the spaces that people think to put outlets, especially as the chargers have grown and (particularly) train operators love putting outlets attached to tables with about 5mm of clearance.
