No. That would be tagging for the renderer. Even if it's generally a
non-visible ref in the outside world (though I've seen three C-roads leak
onto signs in my travels) I believe that it's the render's choice as to
whether they should show up on the maps, not for us to say that there's
something "special" about the fact. A fact's a fact.

I'm not sure whether they're nationally unique references, but they'll be
unique per authority and we've got pretty good bounding areas for those in
OSM now.
