It kind of defeats the purpose. If traffic has to come to a complete
stop anyway, why bother using a roundabout?
But that's an argument for not putting stop signs on roundabouts, not
an argument that a would-be-roundabout with stop signs is not a

Yes, this is my point.
On the other hand, there seems to be enough disagreement over this
issue that it's not worth pursuing. Preprocessing steps in creating
navigation software will just have to notice that the road is very
short, and adjust directions accordingly. This is already something
which has to be done in order to create good navigation software,
otherwise you'll wind up with "turn left onto YYY road, go 3 meters,
make a left onto ZZZ road" rather than "make a U-turn".
