   Thank you for the feedback, @gatorsmile. 
   
   I have three questions to understand your request.
   
   - Do you see the example, 
[SPARK-47307](https://issues.apache.org/jira/browse/SPARK-47307)? What is your 
opinion?
   - We have the following migration guide, do you want to set 
`spark.sql.legacy.chunkBase64String.enabled=true` by default in Apache Spark 
3.5.2?
   
   > Since 3.5.2, the `base64` function will return a non-chunked string. To 
restore the behavior of chunking base64 encoded strings into lines of at most 
76 characters, set `spark.sql.legacy.chunkBase64String.enabled` to `true`.
   
   - If we change the default value, do we still need to revert?
