AWS gives you all the tools you need to shoot your foot off, they also give you all the tools you need to avoid this. I can easily hook up a budget alert to a pushover alert on my phone that is just as likely to wake me up as any alert duty would.

Most people don't have alert duty. I don't want alert duty. I want safety and it's extremely easy to provide it.

You just said that there's a danger of not waking up to a budget alert, and then you say you don't want alert duty. Make up your mind.
