How about for now I only allow dynamic registration (no unregistration)
and just send out when new groups are registered, and also give
userspace a list of registered mc groups when they ask for a family
description? That should make this patch not too big and still leaves
room for dynamic unregistration later.

How does it deal with unregistration currently? If it leaves sockets
subscribed that seems like a bug already, at least if the id was
dynamically generated. Of course it would require the id to be
reused to actually matter.

Hmm. I don't see it kicking out the socket subscriptions in
genl_unregister_family so I guess that bug is present.
