 Right, managed to reproduce it too when "updating" to older revisions.

 > Without `wp-includes/assets/script-loader-packages.php`, the JavaScript
 can not be run (no dependency array) and as it's generated during the
 build processes the remaining instructions in `/src/index.php` are enough.

 Yes, makes sense to test for the existence of `script-loader-
 packages.php`, 48154-update-file-check.diff looks good. Ignoring the `wp-
 includes/assets` directory should fix the above bugs.

 Also thinking we can perhaps do a Grunt `clear` of `/src/wp-
 includes/assets/**` before running Webpack in `dev` mode. This will help
 deleting left-over unversioned files there.
