Shouldn`t be the new Service be autowired by default? I updated my project and switched the setLocale() of the TranslatorInterface with the LocaleAwareInterface but I am getting:

Cannot autowire argument $locale of "App\Controller\UsersController::test()": it references interface "Symfony\Contracts\Translation\LocaleAwareInterface" but no such service exists.

when using$locale->setLocale('en');

Just define the interface in services yaml. I'm not sure if this is the best way, but it will work:

Symfony\Contracts\Translation\LocaleAwareInterface:    alias: 'translator.default'

@nicolas-grekas I recently created a new service that I wanted to make itaware of the locale.

Let's say my service wasEmailSender. I tried to have this class implementLocaleAwareInterface but since this interface is underTranslation namespace it does not feel correct to have a service aboutemails implement anInterface for translation. Furthermore the locale is not used there to define the translation but to define the receiver.

So I was wondering if this could be improved even further and have theLocaleAwareInterface somewhere else.
