shop=farmers_market ? What kind of shop, if any is here? Is it intentionally used instead of https://wiki.openstreetmap.org/wiki/Tag:shop%3Dfarm and https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dmarketplace ? If yes, what is the difference? Should we document this shop value as distinct, valid and useful?
