The VM could only make requests if you add a system call specifically for that purpose. Eg. if you add something like sys_request that takes a URL as argument and some input and output arguments. It's not that the VM couldn't open a socket and handle connections by itself, but it's all closed down. I think when it comes to being integrated into a web server, you ideally want to use the web servers pipeline to make requests, so that you can benefit from the same logging and observability that Drogon (or other solutions) already have. If you allow the VM to make requests on its own, you just have the IP and an open socket. Not much to debug with if (let's say) you have a customer asking about something.
