Yes, I would argue that disused physical objects should be rendered.  A
disused:building=house
is still a house.  An abandoned:building=house is still a house.  Even
ruins:building=house may
still be visible.  Disused non-physical objects should not be rendered: a
disused:amenity=pub
is no longer a pub.  Except there are grey areas, such as disused sports
pitches which are
maintained to some degree (weeds cut down occasionally) but no longer
used.  They could
be re-activated for their original purpose.  Abandoned railway lines pose
yet other problems.

For quarries or buildings disused/abandoned status is a property and is not

Which we do only because (currently, on standard carto)
disused:building=yes doesn't render.

In case of shops it is fundamentally different - disused shop is no longer

Depends.  It might be preferable to use shop=vacant is there is a strong
probability (such
as zoning restrictions) which mean that it won't be converted into a
domestic residence.

Is there some trace of the pub (maybe sign?) or danger of incorrect

Then it makes sense to keep it.

In one case I've mapped, yes.  It's a listed building with a distinctive
old pub sign which
cannot be removed (because it's a listed building).  It closed a couple of
years ago and
as far as I can tell is now a domestic residence.  A mapper passing by
would assume it
is still a pub.  https://goo.gl/maps/nf3S2MfjjV12tqAaA

Though in cases where no trace is left I would delete it (yes, OSM doesn't

Again, near me there are several pubs that have closed but there is a
prospect they will
re-open under new ownership.  One recently had a bad fire 6 or 7 months ago
but has
just re-opened.

And then there are churches and chapels which have closed but not, as yet,
been repurposed.
So building=chapel + disused:amenity=place_of_worship.
