Netherlands has many mini roundabouts AND they follow the regulations of ordinary roundabouts. However, those are the same as for other junctions. So according to the wiki, these roundabouts and mini-roundabouts should not be tagged as roundabouts but as circular junctions, because no priority is implied. Nevertheless these rotaries are massively tagged as roundabouts, and lots of junctions wih a dot or circle in the middle as mini-roundabouts. Because that's what they look like, and that's what they are called: "rotonde" en "mini-rotonde". So far I see no compelling reason to change it. Regardless of legal issues and signage, navigation systems should not advise u-turns on narrow junctions including narrow mini-roundabouts. I guess that is why navigation systems keep telling me to "try and turn around", without telling how and where.
