Review Comment:
I think we should talk about why people would set it to false, is something
like
> Turn off this feature if you are using S3FileIO.listPrefix for listing
bucket prefixes that are not directories. This would ensure correctness and
fail the operation based on S3 requirement when listing against a non-directory
prefix in a directory bucket.
