How does this compare to rclone, as I also asked in a top level comment? rclone can mount S3 as a union mount so it seems to have the same feature set? Have you benchmarked ZeroFS against rclone?

Unless I am missing something, rclone will probably compare similarly to https://www.zerofs.net/zerofs-vs-mountpoint-s3

		One big difference I see is that rclone is MIT licensed, whereas ZeroFS is licensed under AGPL with commercial license also available? https://www.zerofs.net/licensing
