No, NFS only cares that the i_version number has changed, and it's
mainly important if you have two clients trying to simultaneously
access the same file, so they get a signal that they need to
invalidate their locally cached metadata (or data, in the case of
NFSv4).  But Hurd only supports NFSv2, and the performance is such
that I doubt anyone would be all that interested in using a Hurd
server as a NFS server for even a small workgroup, let alone a
department, so this is unlikely to be a big deal.
