I don't think an expenditure cap is so simple. Exactly what happens when you hit it? If you have, let's say, 3 RDS DBs and 20 EC2 instances running and a bunch of stuff in S3 and a few dozen SQS queues and a few DynamoDB tables etc, and your account goes over the limit, how do you decide which service you want to automatically cut?

So 90% of the time I hear these horror stories it's a test/dev account where deleting everything is preferable to getting a bill.

I also don't understand why everyone is assuming

"if I hit threshold X do A, if I hit threshold Y do B" where A and B are some combination of shutting down and deleting resources,

is as difficult as solving NP complete.
