Now ContentTranslation does not publish blank page.
Publishing blank page is useful e.g. when translating categories (which typically contains only categories), as it assist with annoying stuff (maping categories, adding new site link to Wikidata).
Steps to reproduce:
- find some category that contains no content (only categories)
- translate it by ContentTranslation
- result: ContentTranslation will not enable you to publish the translation
- enable ContentTranslation to publish a blank page (preferated)
- do not enable to start translating blank page and show warning with explanation (hardly any sense in doing that)
