I would love to have this feature in Hungarian Wikipedia. There were many instances of incorrect information or untranslated words appearing in infoboxes and in many cases they were noticed only weeks or months later. If Flaggedrevs could mark these pages as needing review, we could spot these additions. It would be great, though, if the communities could decide whether to implement this new feature, so if Russian Wikipedia or any other wikipedia doesn't want it, or tries it and decides against it, it wouldn't be forced on them.
