Thanks for starting this discussion, Chesnay. +1 from my side. It's time to move forward with the ZK support considering the EOL of 3.4 you already mentioned. The benefits we gain from upgrading Curator to 5.x as a consequence is another plus point. Just for reference on the inconsistent state issue you mentioned: FLINK-24543 [1].
