Is it possible to use a custom local (i.e.: en-int)

[fpoirier1]

My client is requesting having a locale called en-int that represent "all the other countries".

I was able to configure next-intl like so :

export const routingConfig = defineRouting({
  locales: ['en-us', 'en-ca', 'fr-ca', 'en-zw', 'en-int'],
  localePrefix: 'as-needed',
  defaultLocale: 'en-us',
});

Which works good until I need to format messages.

t('readtime.minutes', { count: readTime.minutes }) or

  const format = useFormatter();
  const dateTime = new Date(date);
  const formattedDate = format.dateTime(dateTime, {
    year: 'numeric',
    month: 'long',
    day: 'numeric',
  });

I get the error message IntlError: INVALID_MESSAGE: Incorrect locale information provided

It's important to note that I am relying on the locale en-int to do my API calls to my CMS.

Thank you in advance !
