  // Versions 0-1 were removed in Apache Kafka 4.0, Version 2 is the new baseline.
  //
  // Versions 1 and 2 are the same as version 0.
  //
  // Version 3 adds the throttle time to the response.
  //
  // Starting in version 4, on quota violation, brokers send out responses before throttling.
  //
  // Versions 5 and 6 are the same as version 4.
  //
  // Version 7 offsetCommitRequest supports a new field called groupInstanceId to indicate member identity across restarts.
  //
  // Version 8 is the first flexible version.
  //
  // Version 9 is the first version that can be used with the new consumer group protocol (KIP-848). The response is
  // the same as version 8 but can return STALE_MEMBER_EPOCH when the new consumer group protocol is used and
  // GROUP_ID_NOT_FOUND when the group does not exist for both protocols.
