This is great, and I have already started trying to encourage more of this in the areas we are working on (genes, drugs, diseases).  But concerns raised more than 2 years ago now still seem very valid:

I'm particularly concerned about the edit button.  When a Wikipedia user hits edit on an article built using wikidata content, how are they supposed to edit the wikidata content?  Obviously the well-informed can sort out which wikidata item is relevant and which properties are being used and go to edit at wikidata.. but this can't be the solution.  

What is the status of this issue ?

thanks very much
