My initial motivation for this was to let people (who are *not*
maintainers) subscribe to parts of netdev. During previous cycles we
saw ~246 emails a day. If someone is only interested in e.g. IP routing
fishing out the one routing patch a week from all the driver noise is
almost impossible.

Hm, hm. I wasn't thrilled by the idea of sending people a notification
that "you weren't CCed on this patch, here's a link". But depending on
your definition of "hitting the feed" it sounds like we may be able to
insert the CC into the actual email before it hits lore? That'd be
very cool! At least for the lists already migrated from vger to korg?
