Filing only for visibility, the actual behavior change is due to later plugin activation, see rabbitmq/rabbitmq-server#2381.

Manually recover ring state from durable exchanges and bindings
9976605 
Only relevant for some use cases post-3.8.4 which has moved
plugin activation to a later point in the boot cycle, after
topology recovery.

Previously this state was naturally recovered during the topology
recovery boot step.

Closes #45.

Worth mentioning that this partially addresses #17. I'm not currently sure what would be a straightforward way to reconcile the needs of #17 and Jump consistent hashing's approach to ring population. But FWIW the ring repopulation now more stable/predictable w.r.t queue positions on the ring after first node restart.
