It still appears supported, but turned off by default in systemd 216:
CHANGES WITH 216:
+ * journald will no longer forward all local data to another
+ running syslog daemon. This change has been made because
+ rsyslog (which appears to be the most commonly used syslog
+ implementation these days) no longer makes use of this, and
+ instead pulls the data out of the journal on its own. Since
+ forwarding the messages to a non-existant syslog server is
+ more expensive than we assumed we have now turned this
+ off. If you run a syslog server that is not a recent rsyslog
+ version, you have to turn this option on again
+ (ForwardToSyslog= in journald.conf).
So I think we should use imjournal if possible, otherwise fall back
to imuxsock. But I think it should be one or the other, using both
in same config seems wrong to me.
