When I've updated tagging to say removed / destroyed, I've added a
description="Destroyed by bushfire Jan 2020. To be re-built"
eg https://www.openstreetmap.org/node/444672467, so it can be read by
mappers, hopefully preventing them from remapping it, & also map users, so
they don't try & go there!

Seems to work OK?
