The problem is that we don't just have a single fixed ordering.  We have
a different fixed ordering for each type of audit log message.  This
makes refactoring pretty much impossible or very inefficient at best.

I agree that eliminating that dependency on ordering would be a great
thing.  This sounds like a great time to reference Postel's Law or
Robustness Principle first introduced in IETF RFC760 and reworded in
RFC1122: "Be conservative in what you send, be liberal in what you
accept".
