For physical objects, yes.  You wouldn't want
disused:amenity=place_of_worship
to be rendered as a place of worship but you do want disused:building=yes
to be
rendered.  Standard carto doesn't work that way, don't know about any of
the others
because as soon as I realized standard carto doesn't work that way, I
stopped
tagging physical objects with a disused: prefix.

Currently, the best you can do is use the deprecated disused=yes for
physical
objects to get the desired behaviour with standard carto.  There is no
guarantee
that other renderers will honour that.  There is no guarantee that standard
carto
will continue to honour that.

Cue the endless arguments about standard carto not being the only fruit,
don't
tag for the renderer, etc.  Because this is OSM, and rule one of OSM is that
we don't do joined-up thinking.  So give up any hope that we'll get an
agreement with the most common renderers to have a sensible way of tagging
disused buildings so that they render at all (better still would be some
sort of
slight difference from buildings that aren't disused, but that will
probably never
happen).

Yes, I'm feeling cynical right now.  That's because I remember the other
times
this has come up here.
