Review comment:
@cloud-fan - I agree for the point of caller-side code unchanged. I
guess it's just feeling more coherent for others to read and understand code,
when putting `clustering` and `requireAllClusterKeys` together. This was raised
by https://github.com/apache/spark/pull/35574#discussion_r813499279 by
@HeartSaVioR as well. I am curious would adding the field in the middle here
break other external library depending on Spark? I guess otherwise reviewers
already paid the cost to review this PR, so not sure how important to change
the caller-side code back. Just want to understand more here.
