Review Comment:
They would write StreamingListener code just like their rest of
Spark-Connect code. I.e. they have access to only those packages that are
available in Spark-Connect. (they don't import 'connect' version directly).
What that would mean for this class is a bit uncertain to me. If
@HyukjinKwon is ok with this, I am ok.
