If you change the keyfile the metadata is changed and the old keyfile
becomes useless; but if the attacker also has the old metadata file
they can make use of the old keyfile. Likewise if someone has the
metadata you lose the ability to delete all copies of it making
the partition instantaneously unrecoverable.
