That should indeed be the default behavior out of the box with the way the S3 buckets are configured. I have a couple Jekyll sites deployed this way, and a request to the parent directory does get served by the contents in `index.html`. Are you not seeing that behavior?

I'd definitely like to add more variants of the default stack. At the minimum, I'm sure there are folks that prefer `www` redirects to the apex domain, or removing the `www` subdomain altogether.
