In a long message, Zooko Wilcox-O'Hearn wrote, in part:
the person who has the authority to sign the message
can *not* sign new messages
it means that the data is immutable once transmitted, even to
someone who has all of the secrets that the original sender had.
This looks like a notarization use case of crypto, with the attempt to
implement the notarization service without the help of a trusted
[timestamp/historic evidence] third party.
Just my attempt to summarize a lengthy explanation ... no further comments.
