In the elixir ecosystem, we have private package management (plus software BOM support), which probably would be useful to you as it would let you share code internally for your own team. As long as zig's PM system gives you the flexibility to repoint the package manager to your own domain, you'd probably find the availability of some package manager better than bare code management, if for no other reason than it will make it easier to have internal consistency with component versions and dependencies.
