Better way to uncontrolled components?

Hi, in the documentation for uncontrolled components it is shown that we could use ref to access the values in the form, it is not specified why we shouldn't use this approach instead:

const App = () => {
  const file = useRef()
  const submit = (e) => {
    e.preventDefault()
    const form = new FormData(e.target)
    form.append('archivo', file.current.files[0])
    console.log(Array.from(form))
    // even better:
    Object.fromEntries(Array.from(form))
  }

  return (
    <form onSubmit={submit}>
      <div>
        <span>lala</span>
        <input defaultValue='my value' type='text' name='field' />
        <input type='file' ref={file} />
      </div>
      <input type='submit' value='Enviar' />
    </form>
  )
}

I think it's way cleaner as we only have to focus one one potential value, an input of type file. Is there a reason to not use it?

Start with content/docs/uncontrolled-components.md, especially the section describing refs and form values, and review the linked example. Clarify in the documentation whether the proposed FormData and file-ref approach should be used and why, then verify the page presents a clear recommendation for uncontrolled forms.
