I would suggest to leave it, because it seems to lead to some kind of climbing route. --> This path isn't intended for normal hikers.
And it's possible to have path's which aren't very visible.
But we have to improve the tagging, so it resembles the real situation.
@Taktaal I don't understand the access=no either. The intention is to dissallow everything except foot=yes. But I don't like this schema either.
