Why deptree.js isn't minified?

This file has increased by 4MB the size of my application.

Why isn’t minified like the others in the same folder? platforms/android/assets/www/build/

I’m running the build using:

ionic build android --release --prod

I think it’s a bug of ionic-app-scripts v1.1.0. The file shouldn’t even be there. See https://github.com/driftyco/ionic-app-scripts/issues/735
