AFAICT rsyslogd wasn't special-cased in the upstart days, meaning it
would get killed with other upstart services in semi-random order, so
it never was able to log the very last messages. It would get killed
after most services that were defined by a SysV init script though.
I'm not sure how much of a regression there really is; it would depend
on how early rsyslogd gets killed now...

If journald uses some specific configuration/dependency to always be
stopped as late as possible, then maybe that can be applied to the
rsyslogd unit too, so that they get killed virtually together (or even
rsyslogd last, if that's possible). That could solve your issue in
current releases even?
