For the benefit of anyone else looking at this changeset, I've asked slice0 what evidence there is https://osm.mapki.com/history/way/165672226 should be secondary rather than tertiary.
I've also suggested in fairly strong terms that slice0#s attitude to the rest of the Au community needs to change (see e.g. the profile text and diary entries at https://www.openstreetmap.org/user/slice0/diary ).
Best Regards,
Andy (from the DWG)
