Yes, for the reasons you go on to describe:  it is quite possible for an
article to reach a site that knows about the groups via one that doesn't.
Rewriting of headers is evil and should be avoided if humanly possible.
(There are one or two cases, like "Path", where it can't be avoided.)

C News does not gratuitously rewrite headers.
