Out of curiosity, what's you basis for changing the two My Auchan stores from shop=convenience to shop=supermarket? I see you're using iD which is most definitely suggesting to use shop=convenience (based on https://nsi.guide/index.html?t=brands&k=shop&v=convenience&tt=auchan#myauchan-f3ab02), the brand's Wikidata entry (https://www.wikidata.org/wiki/Q115800307) says it's an instance of "convenience store chain", and OSM Wiki (https://wiki.openstreetmap.org/wiki/Tag:shop%3Dsupermarket, https://wiki.openstreetmap.org/wiki/Tag:shop%3Dconvenience) suggests that a supermarket "is large enough to use trolleys". Does any of that contradict what you see on the ground? (your changeset doesn't actually specify if it's based on a survey or local knowledge, so I'm not sure; please consider supplying the source information in the future)
