You have it the wrong way around. Here, ZFS uses many small S3 objects as the storage substrate, rather than physical disks. The value proposition is that this should be definitely cheaper and perhaps more durable than EBS.
Yes that is the value prop. Cheap S3 instead of expensive EBS.
EBS limitations:
- Per-instance throughput caps
- Pay for full provisioned capacity whether filled or not
S3:
- Pay only for what you store
- No per-instance bandwidth limits as long as you have network optimized instance

See s3backer, a FUSE implementation of similar: https://github.com/archiecobbs/s3backer
See prior in kernel ZFS work by Delphix which AFAIK was closed by Delphix management: https://www.youtube.com/watch?v=opW9KhjOQ3Q
BTW this appears to be closed too!
