The problem with lane:n:feature, is say youre approaching traffic lights and you have a right-turn light with a long slip lane and a short left turn lane to avoid the lights, how do you tag this? When you go from lanes=2 to lanes=3, how does a renderer know which side the extra lane is on? If you have a 3-into-2 merge, how do you indicate which lane merges easily? Sometimes you might have a single slip-lane which joins a 2-lane road and becomes 3-lane. Another possibility for this tag, is an extra lane for pick-up/set-down at transport hubs or pull-in bus-stop lane, which doesnt have a barrier to the main way. In which case the lane might have psv tag or something. These are the sort of situations I think were being referred to as not having a standard tagging method yet.
