Hi All

Please find the below KIP which proposes changing the setting 
unclean.leader.election.enabled from true to false. The motivation for this 
change is that it catches out new Kafka users who don’t realise the default 
favours availability over data loss.

This would mean clusters wishing to continue with unclean leader election 
enabled would need to add the appropriate configuration on upgrade. 

Please let me know if you foresee any issue with this change, agree or don’t 
agree.
