it is not just one renderer, OSM-Carto is often seen as standard
implementation and a lot of people are taking it as template when they
develop their own style. Generally the vast majority of data consumers does
neither look at disused / abandoned=yes qualifiers, nor at them as
prefixes. This applies to routing engines, rendering rules and all other
kind of data consumers. Maybe there is someone looking at these "details",
but most don't.

As already mentioned the tricky bit is working out what "disused" means for

that's a problem of tagging then. "landuse" is not suitable to represent a
business. You need an additional tag for this. It might work as a shortcut
in simple cases, but it is not generally working and is not in analogy to
how we map factories or other industrial landuses for example.
