I usually map loops explicitly, but I have occasionally tagged such places
as highway=turning_circle when I wanted to indicate that there was
something there, but didn't want to spend the time drawing a bunch of
loops. In such cases, I've used turning_circle, because it seemed the
least-incorrect tag available.
I think I'd prefer highway=turning_loop. It seems simpler to use one tag
rather than two, since in this case, you could argue that a
turning-area-with-an-island is not really a subtype of a
turning-area-without-an-island. (Though you could address that by saying
that the two cases are highway=turning_circle, turning_circle=island and
highway=turning_circle, turning_circle=open, with the assumption that a
missing turning_circle tag implies turning_circle=open.) I don't think it
would be too hard to add a rendering for highway=turning_loop, so if it
gets general approval and no one else beats me to it, I'll try to put
together a patch against the main rendering for it.
