pNFS, FhGFS, Lustre, Ceph, etc., all of them shall implement their own interface? And userspace needs to address all of them differently?

The NFS and SCSI groups have each defined a standard which Zach's proposal abstracts into a common user API.

Distributed file systems tend to be rather unique and do not have similar standard bodies, but a lot of them could hide server specific implementations under the current proposed interfaces.

What is not a good idea is to drag out the core, simple copy offload discussion for another 5 years to pull in every odd use case :)
