Looking good! One question — should https://www.openstreetmap.org/way/1278802007 be waterway=drain or waterway=ditch? As I understand the tagging scheme, the former implies a bigger construction which I’d associate with urban drainage. The latter is what I believe is typically used for field drains. There are, however, examples where waterway=drain is appropriate for field drainage (e.g. in the Lyth valley), hence my question.
