I don&#x27;t think it&#x27;s as obscure as a problem as you think.<p>I&#x27;ve been trying to learn Go as a sideproject for less than a month, and even I realize what the problem is and how the vendor spec solves it (at least once getting to the end where it says that with vendoring enabled submodules are automatically retrieved with go get.. I don&#x27;t know why they didn&#x27;t get to that earlier.)<p>One of the things I miss the most when working in Go is PHP Composer, and it&#x27;s pretty obvious how the vendor design doc solves the same problem in a more Go idiomatic way.
