I've been mentally trying to apply this to the parks I've mapped, and
it's just not working.

Palisades Park (2.5 sq. km) has two trails that are clearly "main".
However, they're both maintained as access roads for brush-fire trucks,
so I've mapped them as "highway=track" plus appropriate access tags.

Riverside State Park (30+ sq. km) has the headline Centennial Trail
that runs the length of the well-known part of the park.  However, it's
usually not the best (or most popular) way to reach any given section of
the other 90+ km of hiking trails.  It's also a "highway=cycleway,
surface=asphalt, foot=yes" rather than a hiking trail.

Slavin Conservation Area (2.5 sq. km) was intended to have a main loop
trail, but the wetland restoration project was a little too successful
and a section of the loop is now under water.  The trail network that
developed as a result does clearly have a "main" section, but it
doesn't reach the parking lot -- there are three routes of roughly
equal popularity to cover the kilometer from the parking lot to the
main trail.

I'm just getting started at Mount Spokane State Park (50+ sq. km), but
the official trail network is looking like a hub-and-spoke system,
where most of the hubs are parking lots (or former parking lots).
There are some trails that are "main" in the sense that I'll use them
when giving directions to a lost hiker, but that's due to their "can't
miss them" status rather than being the best, shortest, or most popular
route to go somewhere.

"trail=main" might work as a concept for smaller parks with a few
high-attraction features and a well-designed trail system, but for
larger parks, especially where the trail network evolved rather than
being designed, it doesn't.
