Honestly I think that's pretty wrong. Go is designed to let you get coding quickly. It's not designed to make your ultimate solution well designed are easily refactorable. In a few years there's going to be a ton of Go code that becomes almost as bad as C where it becomes untouchable because people quickly threw something together and didn't think about long term design.
