I have a different opinion on this. Usually, in production deployments (atleast whatever I am aware of), database is generally managed at the org/group level. Privacy policies like ACLs are usually done at database level and would need first level management by admins. With such a setup, its feels safer to let database creation done through separate process and let hudi hive sync only alter/create tables (current setup).
Open to hearing other's thoughts.
