I'm kind of surprised that using object storage wasn't a first-class concern. Though I guess if running it at home was the biggest thing, that's not the top priority, but still. Using fast, cheap object stores (often with CDNs in front) has been commonplace for images, videos, and similar content for decades now. For virtually anything that uses some dynamic amount of storage based on user actions, my expectation is that I'll be able to configure it to store and fetch from S3 (or similar).
