It sounds then like you think I am correct on the lower section.

Sounds like we agree about this (between my notes section) being a
difficult edge case, and the issue is about degree of limited access and
frequency of at-grade intersections.

For trunk, I think it needs to be divided, with minor amounts of stuff
on the side (a driveway or business every quarter mile is ok, more not),
reasonably high speed (45 mph min, 50 mph preferred), and at-grade
intersections no more often than once per mile.  But while that seems
consistent with the rough consensus, that's my notion in detail.

As long as everything tagged trunk is at least iffy, I'm happy.   It's
only things that really aren't that bother me enough to write :-)

I'll tend to leave it, since I think more people in OSM lean to
overtagging in iffy cases, and the part north of my northern note is
even more trunky.
