Directory delegations are not related to pNFS but rather to NFSv4.1.
I wasn't involved in their experimental implementation in CITI so I
don't know exactly what were their challenges. I can only guess that
the harder parts were dealing with the name cache rather than
implementing the related NFSv4.1 code.
As far as I know, the benefits demonstrated so far are not good enough
to justify the added complexity.
