String doesn't have to be translatable?

I think we don't have to make

__( 'You\'re using WordPress in a language we don\'t support yet. We\'d love for %2$s to be translated in that language too, but unfortunately, it isn\'t right now. You can change that! Register at %4$s to help translate it!', $this->textdomain )

in https://github.com/Yoast/i18n-module/blob/master/i18n-module.php#L174

translatable, since it only shows for languages which we don't ship. In other words: users only ever get to see the en_US version of this.
