RedHat/IBM does have an Illinois presence so will likely be compelled to add it to their distro, and will likely do it through systemd. So to avoid it getting into any consumer distro you'd have to ship a patch to remove it from systemd.
This is probably all completely irrelevant to StageX since it's a distro designed to be used in containers, AFAICT.
