foundation.min.js in Distribution-ZIP is HUGE

I downloaded the latest Release (6.9.0) from
https://get.foundation/

which leads to
https://static.foundationcss.com/sites-css-latest

The zipfile contains the mentioned js-file in
/js/vendor/foundation.min.js

I assume this is meant to be a production-ready version.
The file however is way too large (532 kB)

compared to the one on github:
https://github.com/foundation/foundation-sites/blob/develop/dist/js/foundation.min.js (193 kB)

Or am I getting something wrong?

Compare /js/vendor/foundation.min.js in the 6.9.0 Distribution-ZIP with dist/js/foundation.min.js on the develop branch. Start by checking the two artifact URLs and determine why their sizes differ; the issue is done when the release contains the intended production build or the difference is explained and corrected.
