Review Comment:
is that really what we want here? to promote a scalar to a list? It seems
strange to me.
Can someone check how other systems handle this case?
@Rafferty97 's initial description in
https://github.com/apache/arrow-rs/issues/9484 says:
> Personally, I would prefer the former, as this "scalar-to-list promotion"
logic feels like an unconventional and unexpected feature to have for a JSON
parser.
I agree
