[opensuse-factory] 20190502 -> 20190506 brings in lightdm on KDE?

During 20190502 -> 20190506 upgrade zypper says: The following 15 NEW packages are going to be installed: lightdm lightdm-gtk-greeter lightdm-gtk-greeter-branding-openSUSE lightdm-gtk-greeter-lang lightdm-lang ... Is lightdm required and/or intended on a machine with KDE patterns installed? IIRC KDE uses sddm. Full log with repos is attached.
