As I understand it (from last time this discussion cropped up here)
JOSM and Potlatch already handle the reversals of :left and :right
tags, which covers most users. You could just as well say that any
way with no matching public GPS trace or alternate source tag should
be removed as there is insufficient information without local
knowledge to know if it is correct or not.
