Thanks for the proposal. You've obviously spent some time writing it up. However, I'm not entirely sold on the idea being worth the effort. The point of the currently-supported approach is that one can and should communicate checksums by a different (and hopefully more reliable) means than what's used for the checksummed data. That advantage is lost if checksums are communicated as part of the data. The proposed passphrases attempt to work around this, but if they're evanescent (as in the proposal) then they're unsuitable for archival data, and if they're permanent they take on the role of the checksums so we're no better off than before.
