Imho, if you want to indicate a turning-circle island, it's
micro-mapping : you should better draw the loop geometry instead of
creating a tag for the geometry (in the same way we don't tag
roundabout flares, we draw separate carriageways if we want).
Btw, current wiki description is funny : "place to turn around .. but
it is not a turning circle".
