True. Time spared on support for the NFSv3 functionality would not bring
us NFSv4 by itself.

Exactly. This is why it helps to mention which kínd of effort might
be most useful.

Yes, strictly speaking, not totally irrelevant.

OTOH NFSv3 itself and the security workarounds come with a cost (not
least the inevitable constraints on the system's management and
evolution/adjustment).

Relying on some mainstream OS with support for NFSv4 does not bring
similar disadvantages.

As a result, without NFSv4 it is hard to expect that NetBSD would be
considered for new NFS installations. :-(
