You're not looking closely enough.

Binaries?  What binaries?

wooledg:~$ ls -ld /sbin/{halt,init,poweroff,reboot,runlevel,shutdown,telinit}
lrwxrwxrwx 1 root root 14 Aug 20 07:50 /sbin/halt -> /bin/systemctl
lrwxrwxrwx 1 root root 20 Aug 20 07:50 /sbin/init -> /lib/systemd/systemd
lrwxrwxrwx 1 root root 14 Aug 20 07:50 /sbin/poweroff -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Aug 20 07:50 /sbin/reboot -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Aug 20 07:50 /sbin/runlevel -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Aug 20 07:50 /sbin/shutdown -> /bin/systemctl
lrwxrwxrwx 1 root root 14 Aug 20 07:50 /sbin/telinit -> /bin/systemctl

systemd-sysv is, as advertised, a package that provides a bunch of
symlinks to replace the core sysvinit commands.

 .
 This package provides the manual pages and links needed for systemd
 to replace sysvinit. Installing systemd-sysv will overwrite /sbin/init with a
 link to systemd.

Seems fairly truthful.
