One thing I would like to bring into your consideration is here, and the https://github.com/auraphp/Aura.Intl/pull/8/files#diff-a377a580d7b1abbe14f408de4ac7ef3fR15

        $di->set('intl_translator_locator', $di->lazyNew('Aura\Intl\TranslatorLocator'));

but the filter expects of type `Aura\Filter\TranslatorInterface` .

So I did created a bundle, so the bundle can change the configuration value that is set 

        $di->params['Aura\Intl\TranslatorLocator']['factory'] = $di->lazyNew('Aura\Filter_Intl_Bundle\TranslatorFactory');
