The original codebase suffered from reinventing the wheel - badly. By composing together well tested high level abstractions, most of the tricky, broken parts could be removed from the responsibility of the application codebase, leaving only appication specific concerns. It could have been done without Go, but Go provides a good set of tools for the task. In C++ land, on the other hand, there isn't such a clear Right Way to do such things (though there are plenty of options).
