I would propose to create a "CSV download" button to replace a tiresome screen scraping process for all of the MediaWiki Special pages.
- During an edit-a-thon I needed a list of articles created by the participants. I was able to get the list via https://en.wikipedia.org/wiki/Special:Contributions (pages created) but then I needed to fallback to screen scraping to produce an Excel list.
- I needed to obtain a list of deleted pages, so I required the list via a tiresome screen scraping of Special:Log?type=delete
- I needed a list of uploaded files in Commons via "Uploaded files". Again only screen scraping with a painfull removing of all other comments and dates was necessary.
Then those CSV lists could be easily used with Quickstatements, AutoWikiBrowser, AC/DC or any other tool that accepts lists of objects or pages.
