Yes, but that's just because I think for simplicity they created one large CSS file that is used for all their components and example pages. That's not very realistic. You're not supposed to do it like this for your own project. Instead if you use Tailwind CSS and PurgeCSS I'm pretty sure you would end up with ~10 or 15 kB of CSS gzipped, maybe less.
That "somebody" would be me then. Sorry for any inconvenience this may have caused. I saw "Latest Release: 1.6" on the djangoproject.com home page, checked if it was on PyPI already (it was), did a "pip install Django" and got 1.6. These together to me seemed to be a pretty good sign that 1.6 was released.
Will wait for the official release announcement next time. Sorry again.
