This is subjective and, as I said, depends on "what we are mapping".
E.g. IF we are mapping the "centrelines of paths of travel" in terms
of geographic location, clearly _messy is more accurate/complete. But
that's a big IF. I'm not saying _messy is better, I'm just saying it's
not *necessarily* worse - it all depends on the goal and the
definition of a "way".

Yes, fair enough. But what if someone wants to mark the geographic
locations of these "turning lanes etc"? Then we go to something line
highway=lane, I guess. But that's off-topic here.
