Yeah, we definitely won't be writing a web app in Go. We can just build it with Drupal and it'll be fine. Most of what we'd use Python or Go for are small services that handle one thing that run in their own container. https://github.com/progrium/gitreceive is a good example of the kind of services that we'll be building (we didn't build gitreceive, obviously, and we probably won't re-implement it because it's already pretty good. Just wanted to give an example)
