I can do this with external tools and build systems (make, cmake, waf, scons + protoc and any other binary that I want) that at the end of the day work nicely with the provided tools. Go on the other hand seems to want to be monolithic. It is the center of your compile and link universe. To me it is quite un-Unix. Not unlike how limiting the import system is. Many of the features of Go make it feel like a walled garden.
