But not everyone uses GNOME and therefore not every distro uses systemd. Slackware still doesn't, and it's not some kind of minimal-for-Docker distro. Edit: Actually I see that GNOME doesn't require (since 3.30?) systemd: it can be used with just elogind. (Slackware actually recently adopted elogind for KDE and Xfce). Gentoo is another distro that doesn't require systemd (it's actually optional).
