I think this is a grade-A #1 good idea.  It is general - I can
already think of lots of situations in which it would be useful.
The network map files, Baby Doc Werner's AIDS postings,
positions in PBM games, newsgroup charters posted to the groups,
answers to common question in newsgroup X, and plenty more.

One caveat: it should be no easier to forge a "Supersedes" field
than a "Cancel" message.  Probably this means only articles from
the same poster can be superseded.
