No sys admin will ever allow a small custom HTTP server to be open to the Internet without a proxy before. Plus, we already have two really great HTTP servers in the UNIX world, Apache and NGINX. In no way a custom HTTP language related framework can cover as much as those two projects.

This trend seems to have started with Rails. It has a few advantages:
1. You can use the embedded server in development and testing. This is *way* easier than installing Apache on your development machine or CI setup and configuring it to point to your application.
2. In production, you can configure Apache or nginx to reverse proxy for the app; this configuration is almost entirely agnostic to the application itself, so you can modify the application's behavior without playing with the frontend web server.
3. The frontend proxy and backend web server communicate over a plain old socket, so they can run as different user accounts or even in separate VMs.
Basically, embedding a web server and reverse proxying for it isolates the application from the frontend server and simplifies the management of both.
