I don't see why this doesn't integrate. E.g. your example
shop=supermarket
level=0

could have the tags added:
level:ref=EG
level:name=Erdgeschoss

This might look unneccessary at first glance (and in many cases it is), but
there are cases with particular floor numbering and naming schemes where it
is helpful.

The min_level-idea doesn't work AFAIK in all cases, where storey heights of
adjacent buildings are different and they are connected by a bridge, and
more general, it doesn't work where levels aren't simply stacked and
uniform for the whole part/buidling but are inclined or have varying
absolute elevations in different rooms (e.g. connected by a ramp). The
min_level of which building should apply? I still suggest to use
building_levels for the amount of all levels of that building part /
building, not the concept of "building_levels=min_level of a neighbouring
building until first level+amount of building levels of the part that is
tagged".

Also buildings with varying floor heights are not depictable (AFAIK).

Some examples:
