Hello ! Please note that the highway tagging is designed for cars : there should be also a highway-like tagging for trucks, for bikes, and for pedestrians.
Plus : there is the commuter point of view and the long-distance point of view :-) I would vote for an importance tag, values from 1 to 6 : for some roads or path we could reach a cool level of details : example : car:importance:commute=1, bike:importance:long-distance=3 We can merge : importance=6 is for cars, bikes ... and commuting and long-distance (usually it is for a dead-end), Importance=5 could still be called highway=unclassified.
