> Services emit metering values that arent directly tied to prices.

Yep. The metering ("Kona") is separated from the billing to such degree that it's basically impossible to find anyone at the company who understands both.

I remember having to work on some metering code, and trying to figure out whether it would result in correct billing that matched our service's documentation. I was basically told off by a more senior engineer for wasting my time on something that was completely tangential and outside of the "engineering" domain entirely.
