There's a handful of syslogds, including busybox-syslogd, and the
ancient sysklogd, among other things. Furthermore, we want to support
upgrades that continue running sysvinit, so we can't make the journal
reader default (unless the syslogd can - like syslog-ng - figure out
which one to use at run time). (iirc the default rsyslog.conf uses
/dev/log, and rsyslog translates that to /run/systemd/journal/syslog if
it detects systemd, thus preserving compatibility.)
