For what it's worth, we (Fly.io) have this feature, and announced it as part of our launch post on HN. But literally no one has asked us to enable it on their apps. So we never made it self service.
I think for most companies, it's better to set the expectation that the service costs money, bursts will cost more money, and then forgive outlier charges once or twice. It's tremendously difficult to compete against the AWS's of the world, putting work into features specifically to minimize how much people spend seems like a good way to fail a company.
