Don't we want to use a memo here?

[mcayuelas-ledger]

I think we can think a little more generic?
In fact, if we add another language in the future

it might be a bit overkill at the moment, but something along the lines of

export const useSupportedLocales = () => {
  const thaiFeature = useFeature("llmThai");
  const greekFeature = useFeature("llmGreek");
  const arabicFeature = useFeature("llmArabic");
  const lithuanianFeature = useFeature("llmLithuanian");

  const features = {
    th: thaiFeature,
    el: greekFeature,
    ar: arabicFeature,
    lt: lithuanianFeature,
  };

  const supportedLocalesFiltered = useMemo(
    () =>
      supportedLocales.filter(locale => {
        const feature = features[locale];
        if (feature && !feature.enabled) {
          return false;
        }
        return true;
      }),
    [thaiFeature?.enabled, greekFeature?.enabled, arabicFeature?.enabled, lithuanianFeature?.enabled],
  );

  return supportedLocalesFiltered;
};
