What are you thinking of exactly?
I suspect that there could be more sharing.

I don't know if anyone's looked into it.
There's a lot of hand-written xdr code (the encoders/decoders
themselves, the maxsz constants in fs/nfs/nfs*xdr.c, the _rsize junk in
fs/nfsd/nfs4proc.c, ...). It seems error-prone to me though I can't
recall if we've had a lot of bugs there in practice.
