> In older KRaft versions, we could see a ConfigRecord for a topic config appear before the TopicRecord in a batch.
> When upgrading from an older KRaft version (e.g., 3.1), the latest code in the KRaft controller hits an NPE when it encounters a ConfigRecord for a topic config before the TopicRecord. This was introduced relatively recently by KAFKA-14457
