The last part was the most insightful for me.

Personally I am pretty damn sure that WSGI no longer carries the importance it had a few years ago. I think it no longer makes sense to merge different applications on the WSGI level together, it should be done on a higher level and JavaScript is a nice way to do that.

Just think about Google's gray bar. You can totally throw such a bar on top of different independent parts of the application by emitting a tiny piece of JavaScript that generates that bar and handles your user session.

I started thinking about it and was like "Right, you can make multiple async requests to hit multiple apps!"
