I don't have a ton of experience with go, just some one off internal tools development, only a few dependencies. That said, I chose to manage my dependencies manually by making a fork of the relevant repositories. Yeah, it would have been nice if the higher order dependencies were automatically resolved, but the whole thing went smoothly, and felt familiar since it had nothing to do with Go at all. Maybe the take away is that a language agnostic dependency manager is what would best benefit Go?
