Emphatically seconded.

I think it's clear that most of us think trunk is something that has
some aspects of divided, particularly high speed, limited access above
and beyond a normal two lane US highway.

I find the trunk designation useful in that it tells the map viewer that
the road is partway to feeling like an Interstate compared to feeling
like a US highway.   Marking roads as trunk when they aren't physically
superior isn't helpful.
