A '-persist start' will fail if the keys are mismatched, since the device can only hold one key, however a '-persist stop' will succeed and even state 'lvmpersist: stopped VG with key 0xgivenkey' even though that's not what happened.
Sure, LVM (like pvremove) has a history of success on no-ops or when deleting things that dont need to be deleted, but I think that after a 'vgchange --persist stop' the user expects no keys to be found on the device(s) afterwards.
