   @wuchong @JingsongLi It would be great if some of your team could take a look at the change in 0cabb99916a64e9637c0fccb9a640d457aaecf4f while removing the `if rt.getStructKind == StructKind.PEEK_FIELDS_NO_EXPAND`. It seems that a couple of execution plans would look nicer if the nullability property is preserved. However, a lot of join tests fail which is why I limit this PR to nested rows.
