A lot of the GP's concerns are around libraries breaking compatability, and upgrading deps being hard, but Go doesn't exactly have all the answers in that regard.
Yeah certainly. I've found that in practice it's not a big problem with Go, you can easily vendor your app's deps, of which there are typically fewer (not 500mb+). Keeping them updated for security reasons is the only drawback of that approach really. I vastly prefer Go's technique compared to a central registry.
