Not only that, but all of the features Go doesn't have means that you don't have to navigate the "which subset of the language does this project use?" problem. Every project uses pretty much the same language features. Similarly, the code formatter is universal and minimally configurable, so the code formatting looks the same across the ecosystem. Virtually everyone uses the same test runner too. Also, you get documentation (including links to third party and standard library packages!) for free--no need to set up a CI pipeline for publishing documentation packages. Same with package hosting--no need to set up a CI pipeline to publish packages. There's a ton of this kind of stuff that amounts to a whole lot of productivity that gets overlooked in all of the pennywise-pound-foolish type-system navel-gazing that programmers fixate on.
