Quorum queues already solve this problem today. They pass a "harsher" fork of Jepsen, according to the RMQ team. Khepri is a newer project that reuses the Raft library developed for quorum queues to store metadata, as a replacement for Mnesia, Erlang's built-in distributed DB. I think that means things like vhosts, users, permissions, etc.
