Hello, Corridor Q shouldn't be a trunk road yet as it is currently disconnected from other trunk roads and it will be a while before the extension past Elkhorn City and the one to Grundy open up. Major highways, especially primary and trunk highways, should be classified based on the other highways that they connect to in the present day rather than what they eventually will connect to in time. This is unless the trunk route along the current alignment of US 460 is rerouted via VA 83/SR 744/Corridor Q/KY 80, which the OSM routers suggests to be more direct than staying on 460.
