That doesn't mean it blindly "mounts" it as a disk and attempts to use it as a filesystem. They're almost certainly using it in a manner that is aware of the specificities of how S3 works.
What if the blind mount works 99.9% of the time? I knew what I was doing was risky but well with in my tolerance for pain. Now that we have a strong consistency my code is fixed. That's pretty impressive.
