Plenty of examples I've come across of roundabouts which are both named and have a reference (similar to a motorway junction number). The roundabouts on the Birmingham ringroad are a good example. The name tag doesnt appear to cause any problems but the ref tag does in that the renderers need to not display the ref on a roundabout in the same way as they show the ref for a normal highway. But these are all rendering issues, not problems with the data.
