Exactly. Even less work is just having a street with no roundabout at all.
Since when is a roundabout about how many roads enter it? A roundabout is a big honkin' (or in some cases, a small honkin'
) circular road, running one way, around something in the middle of it. Other roads attach to it and those coming from the entering roads are required to yield to the traffic already in the roundabout.
In U.S. dictionaries the terms "roundabout", "traffic circle" and "rotary" are synonyms. There's no requirement that there be more than two roads attached.
A couple of thoughts.
1) I didn't say they weren't roundabounts, just that they weren't worth mapping.
2) Although yielding to the traffic is a consideration, its not a universal quality of traffic circles. There are certainly urban signaled circles where "at the roundabout take the second exit" is a useful instruction, but the traffic in the circle doesn't have any right-of-way over the traffic entering the circle as the entries are all signaled.
3) I still don't see the advantage of an instruction that says "at the roundabout continue straight" or "at the roundabout take the first exit," when there are no other roads to take. The roundabout as a corner does confuse me. I prefer "take at left at . . .", to "at the roundabout take the first exit", if the only things I can do are turn left or go back the way I came. If its truly a big honkin' circle, I'd prefer to get a turn right at State Circle and then get a turn right on Main St instruction.

Is it, in fact, still the case now? Have you seen any recent occurrences of whatever the problem behavior is that you've seen? It could very well be that it's already been fixed.
I have not seen recent occurrences, so roundabouts may now be treated differently with regard to this issue.
