the mere thought of changing e-mail to be less permissive than
STD821/822 makes his skin crawl for less rational reasons.

SPF is more permissive than RFC 821:  SPF allows to "aggregate"
unrelated sending MTAs in one "permission" (SPF record).  A more
restrictive approach is BATV, and combining BATV with SPF can
make sense for folks who don't need the "aggregation" feature.

IOW if you ever thought about SPF's include:-mechanism then BATV
likely isn't something for you.
