It looks like adding more control over that would require some fairly
substantial changes to ietf-drums.el. Personally, I've wanted a way to
tell it to ignore a trailing comma: right now it will look at a header
like "To: bob <bob@bob.com>, " and complain that the trailing
comma/space is invalid.

But that seems like it should be a separate bug report.

Do you mean in the customization option type? I see there's a "fixme"
comment there, I can provide a patch to make the types more explicit.

Maybe a note and link in the "Message Headers" section (which seems more
general anyway, and a likely place for a user to look if they were
annoyed by this behavior)?
