Yes that is the most radical form of rate limiting. :)

Right. I'll work on a little XEP for that. And maybe also I'll work to
generalize XEP-0161 a bit more (not just spam, but any kind of abuse).

Thanks for the vote of confidence. :) In fact I was not involved in the
decision because I was on vacation that week, but we have several admins

I agree. I'm working on some ideas here -- like a special forum or
working group (not necessarily part of the XSF) that will work on best
practices for deployment and operationalization of XMPP services,
especially for secure federation. Stay tuned for details.
