Hello. The dev list might be a better place to ask this question. FWIW I believe your interpretation is correct -- the proposal essentially uses two separate clusters, comprising "controllers" and "brokers". N.B. that the brokers cannot become controllers or vice versa.
You can find the discussion thread here: https://lists.apache.org/thread.html/cce5313ebe72bde34bf0da3af5a1723db3ee871667b1fd8edf2ee7ab@%3Cdev.kafka.apache.org%3E You will see I expressed concerns early on that "the proposal still requires separate processes with separate configuration".
