Not sure I understand correctly, but doesn't the current "hash" provide
a lo-fi version of this same approach? Just wondering if it could be
extended rather than started from scratch.

Also, agree that if there's no "signature" from the publisher all
guarantees are from those who compile the catalog. This is not so
different from e.g. Wikipedia, even though the nature of what CKAN does
is different (the process being sort of comparable).
