I wish Vercel (or Zeit at the time) never abandoned their original model of running arbitrary Docker containers at the edge. I understand the desire to focus on one platform, but you could implement a lot more interesting use cases with arbitrary serverless containers, especially if the build process was as smooth and integrated with GitHub as it is for JS (although arguably a big reason for that smoothness is the focus on one platform).
