> We have noticed that the `LiveLeaders` field in the LeaderAndIsrRequest is not used anywhere but still populated by the controller.
> It seems that that field was introduced in AK `0.8.0` and was supposed to be removed in AK `0.8.1`: [https://github.com/apache/kafka/blob/0.8.0/core/src/main/scala/kafka/cluster/Partition.scala#L194.]
> I think that we can safely deprecate the field and stop populating it for all versions > 0.
