CC @yordan-pavlov, I didn't pick this up in the original PR.

I don't think arrow can currently represent the schema that you had created for nullable primitive and string, so this caught my attention while working on a potential fix for the list reader.

good spot @nevi-me , thanks for fixing this; does that have any effect on the benchmark results?

@yordan-pavlov I wasn't paying attention, but I'll check and post a comment here. I don't expect much of a change, because most of the work is done at the leaf, and that wouldn't change.

It's just that this benchmark stood out when there was a failure on my local branch while checking the perf impact of a change I was making.
