I filter by default on Sender:. Why? In general its unique across all
lists, no matter the MLM used (Yahoo groups are the big exception,
sadly). RFC 2369 headers may or may not be there. Checking To/CC
missed BCC's and confuses direct vs list messages for
non-reply-to-munging lists. Sender, with rare exception, is reliable as
a distinguishing factor for all lists.

I wouldn't rate changing Sender as much of a problem. Its an upgrade.
3rd party unrelated systems are expected to have to adapt -- and this is
a pretty minor adaption.
ObNote: Actually my procmail filters are sufficiently generous with
their regexes that the new pattern gets matched just fine, so there!
Nyahh!
