Thanks for doing the follow-up! I'll gradually enable the option on our clusters sometime next week and let you know if we hit any issues.
Assuming we don't run into any roadblocks: How about changing the default of `-zk_use_curator` from False to True for the next release? Then we cane make significant progress with the deprecation while still giving operators the possibility to do a fall-back if necessary.
