Not really, with a roundabout, you have a way you can follow. Where as an area, you'd calculate somewhat of the middle between the two edges to generate a path, as you can't just route on the boundary of the polygon as it might be unwalkable/doesnt make sense in reality
With a polygon you have a perimeter way to follow. From a start node, go around the boundary (as with a roundabout), find the best exit node (as with a roundabout). draw a route line between the two.
