That tags 'what is on the ground'.
To me, it seems to presuppose an unrealistic amount of cleverness
on the part of the renderer, particularly since 'building:use' is not
a common key at all.
For info, I did go through historic key usage in the UK and Ireland for
a renderer and divided historic key usage into "building still exists"
"ruins still exist" and "something still exists but not a building:
https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/9350fcbfa5133245688918b0e77c531976701467/style.lua#L1323
The tags that aren't mentioned there are where "something might once
have existed here" or "I've seen something on the aerial imagery and it
might be historic".
The UK's had almost no imports though; in some places (e.g. the US)
there have been "schools" and "post offices" imported such as
https://www.openstreetmap.org/node/357530584 . I'm sure there was a
post office in that hamlet once, but it almost certainly wasn't in the
field where that node is located.
If I was rendering data for the US I'd likely try and exclude many/most
GNIS imported features (apart from e.g. mountains, which don't move
much) based on rules including them not being edited by other than
mechanical edits post-import.
Example overpass query of a bit of Nevada as an example, showing the
range of GNIS stuff: https://overpass-turbo.eu/s/ud6 .
