Again it's very old school. You have async, you can do something incredible. You can setup real time RPC, propagate pub/sub accross all client and server nodes, provide a transparent tasks queue, enable live settings, etc.

What you are doing here is just "what sync frameworks do, but async". There is no use for that. I can already do it with WSGI frameworks. It works well. It's robust, proven and productive.

If you don't use async to provide novel features that only async enables, what's the point ?
