   > Was also wondering about a potential error message -- not sure atm what error message a user would get if they run against 2.3 brokers and if the error message would be clear. Should we do anything about it?
   
   Not sure either -- maybe you can use the soak test to spin up brokers on 2.2 against this PR and check out the error message + stack trace? I definitely think we should try to catch the error and log a more helpful error message (eg `in 3.0 we changed the default replication factor to -1 which requires brokers to be on 2.3+, please update your brokers or manually set the replication factor config`)
