Hi,
Recently I have found that in the Flink Kafka Connector, the parameter "connector.properties.zookeeper.connect" is made mandatory for users. Therefore without it, Flink would throw an exception saying “Caused by: org.apache.flink.table.api.ValidationException: Could not find required property 'connector.properties.zookeeper.connect'”.
However, as far as I know, for Kafka versions that are currently supported by the universal connector, this setting is not mandatory anymore. Here I would like know if this parameter could be changed to optional, and what are the negative impacts if doing so?

Thanks : )
