Why do we always create an admin client with the same "connector-dlq-adminclient-" id?

Why do we always create an admin client with the same "connector-dlq-adminclient-" id?

kafka/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/Worker.java

Line 958 in 54eff6a

Map<String, Object> adminProps = adminConfigs(id.connector(), "connector-dlq-adminclient-", config, connConfig, connectorClass, connectorClientConfigOverridePolicy, kafkaClusterId, ConnectorType.SINK);

For all other cases, a postfix is ​​added.

Because of this I get "Error registering AppInfo mbean
javax.management.InstanceAlreadyExistsException: kafka.admin.client:type=app-info,id=connector-dlq-adminclient-."
It looks like the ConnectorTaskId should be added.
