I can see reasonable uses for this, like marking a feed of local disk
errors
as not of general interest.

This certainly wouldn't be useful as a security measure. But yeah, a
way to tell the big republishing aggregators that you'd prefer they
didn't republish the feed could be useful, in case they somehow go
ahold of the URL of a non-sensitive (and thus non- encrypted and
authentication-protected), but not-intended-for-public-consumption
feed. Ideally though, such feeds should probably be password
protected, since that wouldn't require aggregator support for an
extension element.
