@helge @silverpill @tchambers i don't think it has anything to do with "openness". it's more akin to a stamp of approval that you can use to verify that the other actor accepted something. you're free to make an "unverified reply" if you wish. by the same principle, we might decide we don't care to verify the sender and therefore drop http signatures, leaving us with "unverified posts". this is no different than any normal web page which can make whatever claims it wants to.
