Who would make a renderer that renders the value of a key like "ref:unsigned"? A roadgeek probably, but I think such a rendering stylesheet should differentiate between signed and unsigned refs. Anyway, using something like "ref:unsigned=OH 315C" to mean "this road is part of Ohio state route 315C but the signs don't say so" sounds perfectly sane to me. Richard didn't say he uses that key *because* it's not rendered; he uses it because it makes sense. The fact that it's not rendered on general-purpose maps justifies the view that the tag won't cause problems.
