Looks like this patch is useful if an ISP is providing
limited service or charging extra fee for increased list
size. Since mailman is not only for ISPs, priority is
lowered. I hope you can keep maintaining this patch here in
the tracker.

For your info, if you add a new variable in mlist class, you
can update exsisting lists' variables through versions.py,
Version.py, and bin/update.
