They are already quite willing to eat costs in cases of legitimate mistakes, compromised credentials, etc for the sake of customer service. I think I've worked with organizations at this point to have a couple hundred thousand dollars worth of bills refunded. The bulk of that was a single $110kUSD bill.

They provide billing estimates and billing data through CloudWatch metrics. This can be used to alert via SMS, email, and other methods. These can be used to trigger lambda functions to implement your own "shut it down" functionality quite easily in a way that actually makes sense for your workload.

What you seem to be advocating for is, more or less, a "pay what you want" model. If they're going to provide services and let you choose the maximum you're willing to pay and expect them to eat the rest, then I don't know how else to describe it.
