I fail to understand your point. For any software, you can create a deb, rpm, ebuild that correctly models the dependencies and install it on the system. No package repo required. You can provide a package repo for any Linux system and install it from there, as for example the varnish people do. Both options provide full dependency resolution without a gatekeeper.
