   Yeah, it's Scala shell's option, right? You can already do `./bin/spark-shell -deprecation` too. After this change, there's no way to disable. It seems too invasive in particular when we think about some other notebooks.
   
   I am less strongly against it if we can optionally control it, e.g., a Spark Shell specific option that negates `-deprecation`.
   
   I know we're discussing about deprecation and removal but this seems overkill by forcing to show warnings without a way to disable it back.
