I think that would be a really useful advance.  It would give a nice
split between the parts of the protocol for nss and (I presume pam) and
the parts that are for other purposes, allowing us to make one part much
simpler than the rest.   

It's quite similar to the way Samba4 implements both IRPC and the struct
bade protocol.
