1) "storage that only lets you put, get, and delete a file"

I'm curious what you mean by this. Depending on your view, Swift certainly does a lot more than this. It also makes sure those files are stored correctly and protected against hardware failure (a non-trivial problem). And from the client API side, there are many other features (versioned writes, CORS, manifests, signed URLs, ACLs, etc etc etc).

But I suppose from a different perspective, Swift "just" reads and writes files.


2) "trivially re-exportable as a filesystem"

There's nothing trivial about exporting an eventually consistent, stateless, distributed object storage system as a filesystem. There are some current projects that offer a bridge, but they often have serious performance problems (as a result of layering protocols with completely different semantics).
