Cancel/Supercede is a useful model -- architecting them out of Usenet is a very bad idea. Ask Clarinet.
Is it? The principal effects of not having the mechanism is a slightly higher disk storage requirement for netnews - something completely unheard of in the annals of USENET.
The downsides of having the mechanism (especially unauthenticated) we see now: official and unofficial squelching of articles that someone doesn't like for whatever arbitrary or situational reason.
<snip> Look just replace "cancel" with "mark as worthless and sign". Then each reader may choose to "honor" the "cancel" or not. If you are reading clari.news.world then you completely "honor" cancels signed by ClariNet. If you are reading alt.religion.scientology, then you have your user agent specifically bring "cancelled" articles to your attention for reading. :-) (As an aside this serves for moderation as well. Just tell your user agent to honor messages marked as "cancelled, signed Bob The Moderator" and you have entered a moderated newsgroup. And the protocol that's gonna bring it to you? NoCeM and its relatives. Real Soon Now, I think.)
