I think the unsigned_ref practice is so common here that we should just keep that practice. Perhaps also a good one to document on the wiki. http://wiki.openstreetmap.org/wiki/Highway_Directions_In_The_United_States may not be the best place for it unless we want to make this page cover the broader scope of highway designation and signage in the U.S. (which I think would be great! but also would require a bit of dedication and time..)
