> not sure I fully understood what you meant

In my 29th and 30th changes is was still learning how to map things - "Is X better mapped as a Y or a Z": https://map.atownsend.org.uk/maps/osm-deep-history/#/way/26579848 .  https://www.openstreetmap.org/changeset/719269 was my 30th changeset, and if you look at the history of something in that https://map.atownsend.org.uk/maps/osm-deep-history/#/way/26579848 you can see a bit of flip-flopping between values.
