Shoot, I only just now saw that new common modules are no longer accepted in favor of #992 for upstreaming to NixOS. To be honest, don't really know what that would involve, or what that would mean for this 7559 entry and the common modules it's pointing to. Any documentation for that process?

We still add new common modules, but we no longer export them in the flake.nix as they are not part of the public interface and therefore users should not rely on them being present.
