Sure, and I would expect the COE called out the operational aspects. No one should have been in a position to be able to trigger that bug trivially (I don't remember if it came from a service, or if they injected the metering record themselves somehow, or quite what. Way too long ago for that)

Most engineers with more than a few years of experience know better than to directly try a stunt like that in production, but they do often get there through painful personal experience. I just wish I hadn't been one of the many that got to suffer from that engineer choosing to learn at that particular moment!
