Hoi,
I would seriously consider this for two reasons. Yes, we can include this kind of information, obviously. It is worthwhile information so that is one.
The most important reason why I want to seriously have this information is because the audience we gain. It is the developers of MediaWiki. They gain first hand experience and consequently they will start first to gain experience and use it and second start to consider it for what else Wikidata can do for them.
My blogpost about Commons and Wikidata was written exactly because Wikidata is not understood and considered by this most vital group for the further development of Wikidata and MediaWiki.
