  As a climber, I don't think we'd want to apply YDS to hiking trails.
To me, YDS should only used for technical routes requiring equipment
(usually). I think "mountain_hiking" is what you can do without
equipment, even if occasionally using your hands for balance.
"alpine_hiking" is when I'm up near or above treeline, often in snow or
large scree fields. A fuzzier category are climber access trails that
most hikers shouldn't use. We have many of those around here.

  I'd be interested in a working group on this, as my map data and maps
are used by multiple rural fire departments and SAR groups. You wouldn't
be surprised by how many people we rescue that misjudged the trail
difficulty... For us though, looking at the subtags helps determine the
type of response and equipment. sac_scale is a bit open to
interpretation based on one's experience, but better than nothing.
