Nominatim is not a general purpose OSM search API (overpass however is),
it is built around the notion of creating address hierarchies of
(correct) OSM data for the purpose of geocoding and reverse geocoding.
It has some support for interesting POIs, but abandoned buildings are
not really of general interest.

In any case I'm not quite sure what your issue with using overpass is?
