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?

從 content/docs/uncontrolled-components.md 開始，尤其查看描述 refs 和表單值的部分，並檢閱連結的範例。在文件中釐清是否應使用所提出的 FormData 和 file-ref 方法，以及原因，然後確認頁面是否對非受控表單給出了明確建議。
