So if I try to update a connector to retain ordering, I get an error:

smpulsaruser@Test-Pulsar-Connector:~/pulsar/main/apache-pulsar-4.1.2$ pulsar-admin sinks update --retain-ordering=true --tenant public --namespace default --name cassandra-test-sink --sink-type cassandra-enhanced --sink-config-file conf/cassandra-sink.yml
Retain Ordering cannot be altered

Reason: Retain Ordering cannot be altered

Which prompts me to ask why there is a flag if this is not allowed. Am I missing some permissions thing?
