Correct.

Since RWPM allows alternate scripts on multiple elements (title, subtitle,
contributors, series name...) this can't be for the whole manifest like in
the Web App Manifest.

"title": {
  "fr": "Vingt mille lieues sous les mers",
  "en": "Twenty Thousand Leagues Under the Sea",
  "ja": "海底二万里"
}
