Would there be any problem in drawing normal roundabout way + mini area 
for the center area (as an optional alternative to the node only 
approach)? ...Enforcing node only for mini_roundabout seems too 
restrictive (The same problem exists with quite many tags actually, and 
then somebody "fixes" those because "wiki says that it must be of certain 
object type" regardless of whether the more physical approach makes more 
sense or no).
