   >For existing tables, this will cause issues with schema evol? or we only 
do. it for new tables?
   
   Then it will break if someone upgrades from 0.8.0 to 0.9.0 on an existing 
table with Flink? I understand the criticality of the feature. but wondering 
how the upgrade process looks. Should we check with users and see?
