High availability solution for MQTT when mirroring queues are deprecated ?

[olacour]

We use RabbitMq with MQTT plugin.
We absolutely need high availability in order to ensure that no message is lost
For this, we have a policy that enforces mirroring on all nodes ({"ha-mode":"all"}) for queues starting with "mqtt-subscription".
Our cluster is made of 3 nodes

We do not have unsynchronization problem since nodes are never added or retired (except when the hardware must be changed)

Is there a plan for the MQTT plugin to support new "Quorum queues" ?
It seems mandatory to us for MQTT to support them before deprecating morroring which is the only solution currently available for HA with MQTT

Thanks for your answers
