Why Kafka use the rebalance strategy of rocketmq

hi,
     Can someone help me find out the reason why kafka use the rebalance strategy of rocketmq. When the rocketmq consumer in rebalance ,it does not stop the consuming job, and would not cause the STW. Without the control of the leader member, this rebalance is more lightweight.

As of Kafka 2.4, Kafka also supports incremental balancing and does
avoid a stop-the-world effect.

Cf.
https://cwiki.apache.org/confluence/display/KAFKA/KIP-429%3A+Kafka+Consumer+Incremental+Rebalance+Protocol

There is also a Kafka Summit talk about it:
