To be practical, I think I will retag the clearly residential roads now tagged as 'unclassified' in my town, to 'residential'. Some roads are now tagged as residential, but the main function is getting through the village. These tend to give access to housing as well, but houses are separated from the road by e.g. broad pedestrian pavements, parking lanes, stretches of greenery, a row of trees, kerbs, and/or separate cycleways.
If e.g. a bus uses such a road I will retag it as unclassified. I would use quaternary if I could be sure of rendering and routing, which I am not.
