THis really makes me wonder where CEE actually belongs in this. Is
anybody using this currently? What area is this supposed to cover that
is not already covered by the journal or rsyslog? Is there really room
for another format besides BSD syslog and journal records? So, what's
our story here with CEE?

To me it appears that CEE isn't widely accepted so far (heck, not even
properly defined as multiple different vocabularies for fields are
floating around), and I am bit unsure where it really fits in the big
picture. I am a bit conservative in adding output formatting for CEE if
it isn't clear that there is a need for CEE, that it's going to stick
around for long and we actually have people using this.

Yes, this would certainly be useful. If rsyslog wants access to the full
data stream systemd generates then using our C APIs is a good choice, it
will get all meta data, and can process them the way they want.

Since the audit logs contain a lot of useful data we definitely want to
acquire auditing as another input for the journal. In fact, Eric has
been working on kernel support to allow the journal to get a copy of the
audit stream without interfering with auditd.
