Hoi,
There is a huge difference between being complete and leaving out essential information. When you consider Ronald Reagan [1], it is essential information that he was a president of the USA and a governor of California. When you only make him an actor and a politician, the information you are left with gives the impression he is more relevant as an actor.
You brought attention to new functionality that is essentially broken. It does not give a fair impression of the Wikidata content. I have been arguing against overly referring to academic tools and standards. For me this announcement is yet another pointer that many of the tools are overrated and only have an "academic relevance.
Thanks,
