I agree shop=luxury is not ideal. I saw this changeset discussion which has more details: https://www.openstreetmap.org/changeset/134837986
This particular shop https://www.openstreetmap.org/node/2642857008 is now a shoe shop by a new name (thanks for updating harg) but I see the same question applies to https://www.openstreetmap.org/node/2642857092 and https://www.openstreetmap.org/node/3340683299 nearby which I also mapped as shop=luxury 11 years ago
