As I read the wiki, there are multiple wiki sections (not just the HFCS 
page) that indicate that the trunk tag is *NOT* exclusively applied to 
limited access roads. e.g. the "US" entry in this table --  
http://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrunk#International_equivalence

Surface expressway: A relatively high-speed divided road (at least 40 MPH 
with a barrier or median separating each direction of traffic), with a 
limited amount of intersections and driveways; **or** a major intercity 
highway. This includes many U.S. Highways (that do not parallel an 
Interstate) and some state highways.

To me, "unpaved" includes gravel surfaced roads (which is the predominant 
surface type of non-state highways in rural Kansas). I'm not inclined to 
mark every gravel road in Kansas as 'track'
