Precisely -- an option in Defaults.py that an admin has to go
actively looking for.  If set, VERP0ish options then appear on a
per-list basis for the specific configuration.

Sample reasoning:

  I have an announcement list and a discussion list.

  They have duplicate membership lists of ~50K members.

  The announcement list is low traffic -- few posts a week.

  The discussion list runs ~150 posts a day.

  I want to VERP the announcement list and share the
  bounce/unsubscribes between the lists (which should be automatic).

  I have considerable disk IO savings (the system is compleatly
  throttled by /var/spool IO contention) if I can bundle the RCPT-TO
  envelope sizes for the announcement list to something large and
  gain the VERP benefits from my low-load announcement list.

This of course is ignoring the human factors, which I may not
consider significant for my user base.

The pressure to survive and rhetoric may make strange bedfellows
