Not the only reason, but we have a distributed workload so HTTP is a better protocol than NFS for our use case.

Internally ZFS is more or less an object store. I seem to recall there was a project to expose this to users directly, similar to how ZPL (filesystem) or ZVOLs are just two different ways to expose the internal object store.

Seems like it could be an interesting approach.
