I think it was, or at least, that's what we were discussing at
https://github.com/apache/spark/pull/11242#discussion_r56891305 Not sure what
the original in this PR was because it was force-pushed. In any event, I
personally agree that a minimum count has a little more motivation, even if I
still don't see when this setting would be used. Where do we disagree ... are
you saying that a problematic `InputFormat` of this form would actually work
everywhere else in Spark?
