The XSF has a number of lists - there's the standards at xmpp.org list,
for example, which is geared toward general stanards work, and
there's various specific lists, such as pubsub at xmpp.org and
social at xmpp.org, both of which might be relevant here.

The problem with sending retraction notices is basically that a
retraction is a deletion, and once we're storing these, it means
storing tombstones. I have a general aversion to storing tombstones.

Here is OK, but social, pubsub, or standards might be best.
