No, you wouldn't. Trunk is the proper classification for major through routes that lack full access control in OSM, regardless of their number of lanes, median (or lack thereof) etc. For example, US 59 from Laredo to Houston varies between a behemoth of a freeway with HOV lanes and a two-lane road with 30 mph speed limits in places, yet it's a major through route throughout for intercity car, bus, and truck traffic. Moreover routes shouldn't be semi-randomly changing classification due to speed limits, lane width, etc. So just passing through a 20 mph zone doesn't demote a road to residential status, and neither does a 75 mph Texas Farm-to-Market route become a trunk just because its speed limit is higher than the legal speed limit in most other states. In any event, once upon a time there were clear and consistent definitions in the Wiki for the USA (I believe the ones currently in "United States roads tagging" are the closest to those)... and then they got duplicated in different places in the wiki willy-nilly and there are now a proliferation of silly ones that are often contradictory. That said if there are isolated bits of routes that aren't major through routes that have gotten upgraded to trunk, by all means demote them back to their appropriate level of importance.
