I think the Key portion is a quite useful way for the upper layer to salt the actual R_Keys as a protection mechanism, and having it would simplify a bunch of defensive code in the NFS/RDMA client. Currently, because the keys are provider-chosen and potentially recycled, there is a latent risk. But, I only want it if ALL future providers support it in some way. If a subset does not, it's not worth coding around the differences.
