I don't actually actually know if there would be any substantial benefit. It's like when I tried PyPy as my django interpreter. It gave a few percent speed increase in "real world" but created extra work for deployment.
I've been using Django non-stop from 0.96, and it just works, and you can build around it. If I was running a trading clearing house, or Instagram, I'd probably care about marginal improvements, and then use another language. But for Django, just tuning the workers per server node, and using django-rq jobs works really well.
Kudos for the enthusiasts working on this though, because 'async' is a new Python feature/meme, and supporting it is just being a good ecosystem player.
