Being an imperfect world, what about the following situation:

A small machine (A) gets a large feed, but doesn't have the room to keep
the articles around for long, so it expires some groups daily and others
every 3 days and yet others every 5 days.  This small site feeds a larger
machine (B) that keeps the articles around for 2 weeks, and it too feeds
other sites.  So a cancel message comes and fails on A and never gets
forwarded to B who still has the article (and quite possibly some of the
sites B feeds).

I tend to agree with the transmitting of cancel messages to downstream
sites even if the cancel message fails. I'm no news guru, so if I messed
this up, flame me gently :-).
