Well, that road is certainly not a good example of what we have in Alaska. Our unpaved roads are all-weather roads and can tolerate a lot of rain. The great majority would not degrade to that condition. They are a mixture of sand, clay and gravel optimized for the purpose and laid down on top of a geotextile base. Fairly stable even for heavy traffic. The "haul road" to the oil fields at Prudhoe Bay are an example of such a road. Do a search in Google Images for "alaska haul road" to see them.
That said, I agree that too much fussiness in assigning surface conditions is overall probably less helpful than just knowing if a road is paved or unpaved. I have driven on classified highways here in Thailand that are tracks in all but name. They're paved but so broken up and pot holed that I've used a tag we haven't discussed in this thread yet, surface_condition, to describe them, e.g., surface_condition=Rough less than 40 kph, and similar. Will these ever get rendered in a meaningful way? Maybe someday, but I'm not holding my breath.
