> if you have some _other_ proposal for how billing and service limits could function Im legitimately interested.

Billing doesn't have to be so complicated you can't calculate it in less than a minute. That's a technical failure. Surely you can imagine a better way? If you really think it can't be better, then it's hard to argue against "brain rot".

Also on most systems it will work perfectly fine to use an estimate of the price per unit when calculating the bill for the last couple hours.

Again, unless you have domain expertise I suspect you are drastically underestimating the complexity of reality. As I alluded to earlier metering, pricing, and billing are _at least_ three separate complicated problems in substantial systems. There are multiple metering dimensions that interact with each other, time, and periodicity at a minimum. Saying “do billing better” without either a thorough understanding of the existing system, or an actual concrete proposal, is not useful.

Being separate systems is fine as long as they can all calculate a number within the time it takes to make a cup of coffee. That's not hard if you actually make it a design goal.

I'm sorry that "prioritize it" isn't very helpful, but it's true. If the calculation takes longer than that, it's a management-induced problem.

If we're positing a system that can already do that, then you need to be more specific about the problem you're describing because it's not obvious.
