That comparison is intentional, for one reason: Go doesn't have any "frameworks", let alone frameworks that are remotely comparable to the productivity offered by Symfony, Django, or Phoenix. The language actively opposes the development of tools like these. At best, we've got libraries that wrap net/http, io/ioutil, etc and moderately increase developer productivity, but there's nothing holistic and opinionated. The closest you can get is something like gRPC, but its not even the whole story, and it also relies on codegen so that's a disqualification in my book.

This isn't just technical; its baked deep into the culture of Go. And that's fine. Its designed for something different.
