The users who actually pay AWS decent money or are likely to pay AWS decent money in the future don't ask for this afaik. People paying $5/month for AWS aren't AWS's target audience and likely contribute negligible revenue to AWS.

People do ask for alerting and monitoring but that's not a hard stop.

Then you get complex issues such as S3 and EBS. As long as there is data you will keep paying so what do you do? Have a hard limit but not really since it doesn't cover them? Delete people's data?
