Yeah, but you can use any number of systems to keep track of it if needed. I'm using git submodules in my current project, which keeps track of what commit you are using. Submodules are flawed in a lot of ways, but as a simple way to to keep a pointer to the appropriate version of an external project they are great. It's a little extra work to set them up, but it's fairly marginal. Check them out with go get, add the repo after the fact with git submodule, and after that just use git submodule to always grab the correct versions.
