I mean, maybe the renderer can follow this logic: all untagged ways
are paved ("good") by default, and they're represented as "bad" if
they include any of the following tags with different values than
those shown:
- tracktype=grade1
- smoothness=excellent/good/intermediateThus, it would ignore the value of the surface tag. This would leave our current tagging system unchanged.
