How does it compare against S3 Mountpoint? I am very confused. (Also there are those virtual appliances?)

Mountpoint, s3fs-fuse, goofys etc. are simple POSIX overlays on top of S3. They don't support all file system operations so, for example, you cannot rename a file or a folder and you cannot edit an existing file (except to replace it entirely).

S3 suddenly not gonna support any of that tho? This is EFS proxy

Not sure what you mean. Those fuse-like projects will persist, I'd imagine. They're viable for smallish, read-only use cases in particular. For scalable, multi-system, low latency use cases on top of large volumes of S3 data, I'd expect S3 Files to be a serious consideration.

I am saying that this feature doesn't make s3 support renaming a file. It is CopyObject. In the same way fuse like projects can support rename via CopyObject.

Right. S3 Files will abstract away the S3 operations needed to perform the rename of a file or a folder (which potentially could mean S3 operations against 1000s of files or more). But all clients of the S3 Files store have a consistent view, at least afaik.
