That's not what I meant. I meant, once it becomes normal for projects to accept this as standard, more will use/require it. Maybe not the systemd version specifically, but the general concept. Sure, you can always fork it and create a version free from it, but eventually it'll be too much for any individual to want to deal with and the standards will shift. There will probably always be a distro that doesn't have any of it, but it'll become increasingly isolated and incompatible.
