There is a paper written proposing FIRES, which was written with the financial support of @nivenly. I'd reached out and received extensive peer review from various active members of the fediverse who specialise either in technical, trust & safety, or social areas.
Following their peer-review, I decided that I needed to rework the proposal to outline things clearer, which is why I've not yet published it.
FIRES outlines a few different things, one of those being a different model of federation management, not centered on binary decisions of "blocking or not", but instead a more firewall based approach: allow / filter / reject.
FIRES is also not focused exclusively on domain based federation management, but looks at issues that will become more pertinent as the Fediverse grows, for instance Hashtag or Link management.
