Relying on aapt2 for list of locale is not a good idea.
Most apps depend on compat libraries which are supported in a ton of languages (85). However most apps dont support more than English or a few other.
If the app is not minified to remove unnecessary resources/translations then everything gets packaged in the apk. Technically the app supports all 85 languages but it might be just be a few string which are coming from compat library in all languages.
The best judge of what languages a dApp is supporting the developer and they should explicitly specify which locales are supported rather than relying on aapt2 to extract this.
