Fork time? Maybe all the anti-systemd zealots were right all along...

Edit: To address whether it is likely that this change will affect users: Gnome is planning a stronger dependence on userdb, the part of systemd where this change is being implemented. https://blogs.gnome.org/adrianvovk/2025/06/10/gnome-systemd-dependencies/

Final Edit: The PR has been merged into main.
