Hello,
Since Wikidata is awesome and now replaced all of Template:Link FA and its similar templates with badges. We decided to archive featured.py and keep it for historical reasons. The script is moved to "archive" folder in scripts directory. You still can run it using "python pwb.py featured" and some tests will be ran over the script but it won't be maintained anymore. It would be good to write a new script to add badges to Wikidata Even though it's a easy task that humans should do ;). This change is merged in master branch but we'll port it to 2.0 branch soon so if you still use this script in your wiki please note this deprecation. 

Also it's the first script to be archived, I think we can archive a lot more now.

Best
