I suspect the most-used GUI agents don't provide killfiles at all :-( .
But I would like to hear further opinions on what typical killfiles
actually do, because my own newsreader (nn) seems to do them completely
differently from all others.

Yes, but we cannot realistically expect users' hacked scripts to be fully
compliant, and so anything that is done to make them work regardless (it
is called being "conservative in what you generate") is a Good Thing. And
in this case it costs nothing to do it the way we recommend, so there is
no good argument to do it any other way.
