text: commented in https://www.openstreetmap.org/changeset/74160143 with the usual bryan housel baiting; my analysis with p2 was there were several junctions not connected to the original way (trivial to fix), but the turn restrictions of the two ways were different, and as this is my first introduction to such things other than seeing the icon, lacking even a basic understanding of the principles, and my p2 rather pressed for display space, i figured i'd abort my work-in-progress detaching the newer way.
