Go and vim don't have "distributed package managers"; they just punt on package management altogether. The next step up from that is a centralized package management system, and if you care that much you'll probably build in some notion of versions (even if they're nondeterministic or otherwise broken, as in the case of pip, npm, and many Linux package managers). Building a distributed package manager is quite a lot more work.
