The "Articles data" export would be much more useful with stated username.
Use case: A competition is happening on several wikis (like Esperanto Wikipedia, and Esperanto Wikivoyage). Articles on wiki A are getting more point per byte than articles on wiki B (in the Esperanto community we are already using this strategy to focus editors on underdeveloped projects). While using only online Dashboard, a facilitator would have to wait several hours every time when changing from tracking articles from wiki A to wiki B. But it is quite easy to calculate offline in CVS.
