That's reasonable but not _quite_ true. highway=unclassified is often used in urban areas to denote a minor distributor road. https://www.openstreetmap.org/way/145016745 is a good example (https://goo.gl/maps/YUc6XfuA5wQ2 if you'll excuse the Google Street View link). It's the distributor road for that estate, and of greater importance than the largely cul-de-sac residential roads going off it; but doesn't have a significant through-traffic purpose nor the engineering standards that would imply highway=tertiary. > [...] > From OSRM profiles it isnt - So it doesnt make a difference for at > least OSRM. OSRM's default profiles don't measure importance, only speed, and are fairly blunt instruments which aren't used unmodified by anyone who's serious about quality routing results. (Mapbox, OSRM's sponsors, override them with traffic speed data, for example.) I wouldn't count them as a useful indicator.
