The formatting utility is really just a side effect of the decisions to Go team made regarding syntax and semantics in the language. There's also a tool to automatically update your code if the language changes (this was important during the days of rapid churn, where your programs would break every week).

They made some very opinionated choices and have largely stuck by them. You can't have an unused variable, it just won't compile. What a pain, right? Well, if there's one thing I've learned from compiling open source code, it's that you CANNOT trust programmers to clean up their code before releasing it--just play "count the unused variable warnings" next time you compile pretty much any Linux program.
