Hoi,
The use case I have is to find what people are looking for and cannot find. This is not restricted to "red links". The fact that one template or other construct does not exist is NOT what people are looking for. They look for things like "Obama" "Barack Obama" etc.. They will only find this when there is an article or they will find it when WD-Search is enabled. They will not find it when they use a script that is specific to their language when there is no article.
The objective is that people can add labels to the Wikidata items in order to enable search results using WD-Search, search in Wikidata or search in Reasonator. Additionally such labels will become available in Reasonator or Wikidata when that item is used in a statement. In addition to this Reasonator will show its "backlinks" in many instances.
Consequently, the point of this data is to enable activities that will improve user experience directly. It is not an academic exercise that provides nice to have information.
Thanks,
