I think in all the critical pain points all relatively popular languages used for web development have a well thought out story. I think there's nothing about the "pipeline" that's a huge bottleneck for a well-seasoned developer anymore. At least there shouldn't be. It's more about (a) getting things spec'd out well, and (b) execution.
This is available with many other languages as well, i.e. https://github.com/cosmtrek/air
It may require an external tool, but the deployment experience is a lot simpler for Go than PHP.
