It looks like the above ticket is slightly different, and we should maintain the previous behavior for produce.

> In [https://github.com/apache/kafka/pull/15968/files], we changed the authorization logic slightly. If a produce request includes a topic name that doesn't exist and is not authorized, it now returns an UNKNOWN_TOPIC_OR_PARTITION error. Since topic name is sensitive information, it should return a TOPIC_AUTHORIZATION_FAILED error as before that PR.
> {code:java}
>         else if (!metadataCache.contains(topicPartition))
>           nonExistingTopicResponses += new TopicIdPartition(topicId, topicPartition) -> new PartitionResponse(Errors.UNKNOWN_TOPIC_OR_PARTITION)
> {code}
