according to the wiki,
On which areas is it possible to add landuse=retail?

                Areas which are mixed with residential/commercial since
                some shops exist in the ground floor and of course
                locations which are only used for retail. It is not
                necessary to compare the number of shops with the number
                of flats.

reads to me, like most of the page, as a bad translation.
I tend to agree, as I would go there to go SHOPPING (maths is hard) to annoy the residents, which I would not expect to find in a purely residential area which I would visit solely to annoy the residents.
