I expect that that all this is because of request
to add passphrase with only master key knowledge
(admin forgotten password, but encrypted volume still active)

See http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/3982

Anyway, it is already documented upstream (lvm2 2.02.62/ dm-1.02.45).
