text: i analysed the second (at v2) of the untagged ways you listed, and traced it back to v1, also untagged, in a changeset that created three relations, all proper and none including the untagged way, so i threw out a changeset comment at https://www.openstreetmap.org/changeset/74988384 in hopes of getting an explanation.
  
  i'll look at the first, at v9, sometime when i have more time and tire of watching the rain of the last four days gently to violently descending onto the burnt forest hillsides of last year or fail to struggle to find my way down the hillside into town.  obviously the way i tried already today is a path that is unsuitable with steep slopes of slippery irregular rocks during the heavy rains of these days, so plan b is to come into effect.
  
  more later.
