Currently, the TranslatableInterface implementation looks like this:

interface TranslatableInterface
{
    public function trans(TranslatorInterface $translator, ?string $locale = null): string;
}

and the TranslatorInterface declaration looks like this

interface TranslatorInterface
{
    public function trans(string $id, array $parameters = [], ?string $domain = null, ?string $locale = null): string;

    public function getLocale(): string;
}

It is not possible to pass parameters to the translator if the object implements TranslatableInterface.

In my opinion, we should add $parameters and also $domain to the trans() method in TranslatableInterface to make these mechanisms consistent.
