If the 'standard map' starts rendering 'disused=yes' the same way as
'disused:*=*' (presently not rendered) then what?

The problem is not with the tagging. The problem is with your
requirement for rendering.

My thinking is that both 'disused=yes' and 'disused:*=* tag the same
condition. As such they should be treated equally by renders.
The only reason why there is a preference for 'disused=yes' is that the
present 'standard' render is ignoring it.
If you want physical objects with tagging for disused, abandoned, etc
rendered on the 'standard' map then put a pull request in.
Stop tagging for the render.
