Amazon CloudFront Adds Default Root Object Capability

My guess had been that Amazon was stalling to prevent a flood of low-volume AWS accounts simply to host dirt cheap static websites.
Now, if your website doesn't require server side scripting, you can literally go from paying a few bucks a month for cheap hosting to spending only pennies using Amazon S3 and CloudFront to host your entire site - reliably and quickly. I'm not familiar with other cloud file providers, so if this was possible before Amazon's latest announcement, I'd love to know.
This is talking about allowing you to assign a default root document, e.g. a index.html so that requests to (e.g.) http://cache.mydomain.com/ will return something.
