When the min_zooms were setup initially there was an assumption that highway=unclassified were literally unclassified / worse than highway=residential at min_zoom: 12.
But in fact, the OSM wiki states:
The least most important through roads in a country's system – i.e. minor roads
of a lower classification than tertiary, but which serve a purpose other than access
to properties. Often link villages and hamlets. (The word 'unclassified' is a historical
artefact of the UK road system and does not mean that the classification is unknown;
you can use highway=road for that.)
- What did you expect to see?
If that's the case, they should be min_zoom: 11 like tertiary (but let's keep the kind: minor_road):
- What map location are you having problems with?
The fish hatchery road is just as important arterial as the grey road leading south of Loa.
