In my testing, only `controller.listener.names` cannot be lowercase. Other fields like `listeners`, `advertised.listeners`, and `listener.security.protocol.map` can accept lowercase controller listener name. If we don't want to change the behavior, I recommend to add validation to KafkaConfig, so users don't get unclear message like following. ``` requirement failed: The listeners config must only contain KRaft controller listeners from controller.listener.names when process.roles=controller ``` They should get clear message like: ``` requirement failed: controller.listener.names doesn't allow lowercase ``` -- This is an automated message from the Apache Git Service.
