Is that a question, or actually a request?

Sorry, I should have been more clear:

Please add Composer support to the Nuke extension, so that the extension can be installed and updated easily with Composer.

(It's a request; I would submit a pull request, but I'm not really sure how to do that here, and anyway it'll also require someone to add it to the MediaWiki Packagist account. I phrased it poorly because I didn't want to come across as demanding.)

Patches always welcome. :) If you want to give it a try, please use developer access to submit this as a Git branch directly into Gerrit. Putting your branch in Git makes it easier to review it quickly. If you don't want to set up Git/Gerrit, you can also use the Gerrit Patch Uploader. If you need help or if something is unclear I'd recommend to ask in the #wikimedia-dev IRC channel.
