Yes, [amenity=hotel, involuntary=yes] is a poor way to tag prison in
the same yes as using [shop=convenience; disused=yes] is a poor way to
tag something where only remains of shop are present and it is
impossible to buy anything.

tagging for renderer to force data consumers to process objects that are
no longer existing.
