You're right. The draft is still a draft. I'm gonna add the fixes for configuration and savepoint settings soon. I needed to create the draft first because I wanted to link it to [FLINK-23154](https://issues.apache.org/jira/browse/FLINK-23154). -- This is an automated message from the Apache Git Service.
