Hello, townlion!

I noticed your updates near Moyenmoutier, and wondered: why don't you use the same points on two adjacent (multi)polygons, for instance here: https://www.openstreetmap.org/way/1312619373

Keeping a slight buffer between adjacent polygons gives one the impression that there is an unidentified something between them, which may be useful when there is, say, a hedge, but when there is nothing, is that not basically cluttering the database with near-identical, near-redundant polygon points? What is the added value for keeping such a buffer?
