      * You could still add a handler to the global pipeline, but have

        every mailing list, but it should be fairly minimal in the
        scheme of things

I once added a maybe-log-and-return handler at every point in the
pipeline on our busiest list.  No effect on load.  I dunno, if you're
handling a million posts a day you might notice that.  But handler
calling is way down in the scheme of CPU suckers compared to spam and
virus filtering.

I'm unwilling to add to the global pipeline simply because there's no
such thing as a 100% safe edit, not because I'm worried about function
call overhead in Python.
