I'm really growing tired of significant effort development effort going to dealing with deployment on the part of our stack that isn't written in Go. The Go side, deployment is replace binary, restart app, done. The Python and Javascript code we maintain takes significant effort to deploy, and builds can be brittle due to dependency issues.

There are, but the way go does deployments plays to Unix's strengths.
