Fortunately, we will not have to do that in OpenStreetMap Carto, as we
will not be supporting the style of tagging where one tag says what
something is, then another tag saying it's not really that, but used
to be, or will be. We do not want to encourage the use of disused=yes,
abandoned=yes, or similar tags.
Sub tags give *extra* data about an entity.
A pub that's closed down it's still recognisable as a pub. It's not a
park bench or a multi-storey car park. It's just closed. This should be
described in sub tags.
Similarly a canal that's derelict hasn't morphed into an airplane
runway. Use sub tags to describe its condition.
Expecting mappers to change tagging because renderers are unwilling to
add a few lines of code is the tail wagging the dog & we don't want to
encourage that.
