Yes, but...

...doesn't it? In my experience, *every* OS, including "mainstream"
ones, comes with its own constraints on system mangement, evolution,
and adjustment. It's a question of tradeoffs: which set of constraints
is less of a problem for the use case in question?

Is it? My feeling - deriving largely from my experience - is that NFS
is far more likely to be deployed in a private internal network than
over relatively attackable networks like the open Internet. Do you
have reason to think that feeling is wrong in the large, that "new NFS
installations" predominantly have threat models where on-the-wire
attacks are significant enough for them to find NFSv3 unacceptable?
(Honestly, my guess would be that most of them have not even formulated
their threat model.)
