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:<br>

<br>
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".<br>
<br>
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
<a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/node/357530584">https://www.openstreetmap.org/node/357530584</a> . 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.<br>
<br>
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.<br>
<br>
Example overpass query of a bit of Nevada as an example, showing the
range of GNIS stuff: <a class="moz-txt-link-freetext" href="https://overpass-turbo.eu/s/ud6">https://overpass-turbo.eu/s/ud6</a> .<br>
