IMO an apartment building with shops on the first floor is still an
apartment building. Even the description of building=apartments
mentions "May also have retail outlets on the ground floor".

Even without any additional tags, if there are within the building
nodes or areas with suitable amenity= or shop= tags, we'd already know
some parts of it are used for something else than apartments (even if
smaller office=* may be operating in the apartments). The idea to
further describe the parts or the building is one good way to proceed.

OTOH, if it looks like a shopping center but has some apartments on
the top floor(s), most people would still call the whole a retail
building or supermarket. I doubt there are next to none edge cases
where the classification would vary between mappers.
