If there is a chance of being readded, don't delete it and instead add the life cycle prefix.

For instance this may have been better tagged with the abandoned prefix.

This will keep it from being rendered/used, but it also keeps people from accidentally readding it from old maps / aerials.

This gets all new mappers as the ID editor does not make it obvious.
