+#### Broker

Review comment:
       I think it is worth adding this PR to the broker's list of changes: https://github.com/apache/pulsar/pull/10223. It introduces a deprecated field as well as the preferred field. No fields will be removed until 3.0.0 (presumably), but I think we should advertise the change/deprecation here.
