I'm also a fan of the dedicated line, my primary interest being pedestrian accessibility + QA-ability of such data.
I keep thinking, "hey, I'll go map a curb line!" and run into a related issue: I can definitely map barrier=kerb and kerb=raised when one of those exists along a path - could be near a sidewalk, could be a traffic island, etc. But would it be an oxymoron to map barrier=kerb and kerb=flush (or kerb=lowered)? I don't think I would call that a barrier. However, it is definitely what happens to the curb along most city blocks - transitions from raised to lowered to flush to rolled. I would find it much more useful to know the curb state along a continuing line (set of ways) than to see a bunch of disconnected kerb=raised lines or a kerb=raised line with kerb=* nodes indicating a change (particularly since direction is ambiguous for a node). All of this is to say, what would you think of a way that only had kerb=lowered? Should there be a barrier=kerb tag there? Or *=kerb?
