Here it is, without systemd-sysv:

# logger -t TEST 1234
# tail -1 /var/log/syslog
Sep  4 22:36:10 hostname TEST: 1234


# dpkg -l|grep systemd
ii  libpam-systemd:amd64
214-1                                 amd64        system and service
manager - PAM module
ii  libsystemd-daemon0:amd64               214-1
         amd64        systemd utility library (deprecated)
ii  libsystemd-id128-0:amd64               214-1
         amd64        systemd 128 bit ID utility library (deprecated)
ii  libsystemd-journal0:amd64              214-1
         amd64        systemd journal utility library (deprecated)
ii  libsystemd-login0:amd64                214-1
         amd64        systemd login utility library (deprecated)
ii  libsystemd0:amd64                      214-1
         amd64        systemd utility library
ii  systemd                                214-1
         amd64        system and service manager
ii  systemd-shim                           7-2exp1
         amd64        shim for systemd

# apt-get install systemd-sysv=214-1
# reboot

Now with systed-sysv:

# logger -t TEST 1234
# tail -1 /var/log/syslog
Sep  4 22:38:09 hostname rsyslogd: [origin software="rsyslogd"
swVersion="8.4.0" x-pid="2886" x-info="http://www.rsyslog.com"] exiting
on signal 15.

# journalctl --system|tail -1
Ruj 04 22:40:13 rigel TEST[2957]: 1234

# systemctl status syslog.socket rsyslog.service

As you can see expected behavior is changed, and even worse, that's done
silently, without any warning and no explanation in documentation. It
also breaks unrelated packages like logcheck, etc (thus likely a RC bug).
