I'd argue that stateful is really hard to get

that state on the server when the server crashes?
NFS seems simple in hindsight but like a lot of things, getting to that
simple wasn't chance, it was designed to be stateless because nobody
had a way to save the state in any reasonable way.
I won't disagree with you.
I remember that stateful vs. stateless was one of the big technical
debates of the time, and I remember that (my impression of) the general
feeling was that stateful was better but much harder to do / get right.
(Again, I don't want to start another long thread over this, especially
as I don't really remember any more than what I just wrote.)
So we can downgrade "stateful" from "good" to "different"
and let
it go at that. :-)
