Since d34938aa75af90ae2c82363c3a6948742cfebc00 there are few translations in the extra domain now, so it's meaningless to separate translation domains into two to prevent unnecessary ("extra" as it says) translations bundled in the app itself. Rather, some translators may not recognize the extra domain and it remains old or untranslated.
Same fix with https://github.com/ryonakano/pinit/pull/180.
