What's the point of createResource data.error if upper onErrors or boundaries get triggered?

I was expecting to use it something like this:

const [data] = createResource(id, fetcher);

return (
  <>
    {data.error
      ? 'Error'
      : data().name
    }
  </>
);

const [data] = createResource(id, fetcher);

return (
  <>
    {data.error
      ? 'Error'
      : data().name
    }
  </>
);
