> Point 3 is interesting, does it work across non-apt package managers? At the very least it's not harmful. You could use something like repology or your own index to identify equivalent packages and then install them. Really what you'd want would be a package manager-agnostic way to declare dependencies on things outside the Node universe, and then plugins for NPM that could use to assert they were satisfied in an appropriate per-package-manager way, and maybe optionally try to install them for you using the appropriate external package manager. But the packagers for Node projects wouldn't be writing the mechanisms for that, they'd just be declaring the deps.
