Mapnik renders highway=unsurfaced. That seems like a pretty good sign
it's a common tag, even if the OSM wiki doesn't include it.
I think this makes a lot of sense, as I've never seen an arterial that
was gravel. I view the surface= tag as being more descriptive of the
highway= value. For example, if the road is unsurfaced (which to me
means gravel), I might want to know how big the gravel is or whether
it is more dirt than gravel.
I view highway=track to mean dirt roads with no gravel (e.g. 4wd roads).
