This is backed up by https://wiki.openstreetmap.org/wiki/Key:highway#Assumptions To quote: "Only highway=motorway/motorway_link implies anything about quality. Other road types, from highway=trunk through highway=tertiary to highway=residential=residential/service or highway=path/footway/cycleway/track do not imply anything about road quality. In area with poor infrastructure road forming main road network, of the highest importance in region should be tagged highway=trunk - no matter whether it is high-quality wide asphalt road or narrow low-quality tract worse than highway=service in other regions. Some primary roads in Africa are unpaved. In absence of surface, tracktype and other tags describing quality of road one may try to extrapolate this information from value of highway tag. Note that this needs tuning for every region. Typical highway=primary may be drastically different in various places across the planet. It is highly recommended to add and use tags describing road quality like surface. In one region it may be obvious that all highway=tertiary are paved and highway=track unpaved but no assumption like that will work worldwide. Also, tagging at least some common values allows to automatically build set of defaults for each area." I guess end of the day if we say highway=cycleway can only be used for paved urban bicycle paths and not mountain bike tracks, bicycle=designated + mtb:scale=* could still be used to find mountain bike tracks regardless of the highway key, it's just this is not what current usage and the wiki says and makes it harder to distinguish shared paths from exclusive mountain bike tracks.
