Having end-user hat on me I can say, that over a decade we are moving scientific data around the world with server-side-copy, or 3rd-party copy as we call it. While we more-and-more use NFS (pNFS) for data access, we always need a second protocol, like FTP or WebDAV, to perform efficient data movement. I am not deep in kernel internals, but there must be a very good reason to block such functionality in NFS. Such functionality will drastically simplify our workflow. And I am sure, we are not the only users of it.
