Yes, that is documented in the man page. If a "target" requests foo.service, 
and this doesn't exist, it will try to start /etc/init.d/rc

This isn't what I'm talking about. I'm talking about the boot process running 
/etc/init.d/rc <runlevel> on boot. In /var/log/boot.msg you can see the log 
messages from "Master Resource Control" which come from this script.

But I haven't been able to find any place where this gets run. I've greped 
myself bloody in the source code and in the configuration files, and I still 
cannot find this

Looks like it's still working, yes

Perhaps. What worries me is that the quickie fix/workaround appears to no 
longer be there if they do fail

But RUN_PARALLEL is interpreted by /etc/init.d/rc so maybe it will still work 
after all. I'm just worried that the future plan is to migrate away from this 
to a "pure" systemd setup, and then it will be really gone
