Yes, I agree with you, accepting zero stateid is very important for the server.
However, our NFS4 server implementation is still in the early stages
of development so we intentionally have left this feature outside for
now.
So our intention is to run pynfs tests for other features we have
already implemented.
And yes, I would propose to make a dedicated test for a special
stateid feature (if it's not done yet).

Thanks!
