This is missing the point. I only want to point out that apparently roundtrip=yes without any additional tagging is being used as meaning "this route is a loop" and "round-trip=no" as meaning it's an A-to-b route. This should remain valid. And let us consider how to cater for other cases. Any retagging would mean a lot of manual work. I cannot see any simple way (leaving out AI) to determine whether any given route is a loop or something else.
