  // Versions 0-1 were removed in Apache Kafka 4.0, Version 2 is the new baseline.
  //
  // Version 1 adds a per-topic error message string.
  //
  // Version 2 adds the throttle time.
  //
  // Starting in version 3, on quota violation, brokers send out responses before throttling.
  //
  // Version 4 makes partitions/replicationFactor optional even when assignments are not present (KIP-464).
  //
  // Version 5 is the first flexible version.
  // Version 5 also returns topic configs in the response (KIP-525).
  //
  // Version 6 is identical to version 5 but may return a THROTTLING_QUOTA_EXCEEDED error
  // in the response if the topics creation is throttled (KIP-599).
  //
  // Version 7 returns the topic ID of the newly created topic if creation is successful.
