Make it much more obvious that the use of NQNFS is discouraged (the

NQNFS code is ancient, bug-ridden, and should probably be removed).
The wording here was very confusing; it was easy to get the impression
that NQNFS is an extension to NFSv3 when in fact it just uses some
NFSv3-like extensions on top of NFSv2. As witnessed by the mailing
lists and PRs, some people were reading the description and deciding
that NQNFS was what they wanted to use.

Use the leasing extensions to the NFS Version 3 protocol
to maintain cache consistency.
This protocol Version 2, referred to as Not Quite Nfs (NQNFS),
is only supported by this updated release of NFS code.
(It is not backwards compatible with the release of NQNFS that went out on
4.4BSD-Lite.
To interoperate with a 4.4BSD-Lite NFS system you will have to
avoid this option until you have had an opportunity to upgrade the NFS code
on all your 4.4BSD-Lite based systems.)
Use the Not Quite NFS (NQNFS) protocol.
This experimental protocol is NFS Version 2 with leasing extensions
similar to those found in NFS Version 3.
The interoperability of this protocol with other systems is
very limited and its implementation is not widely used.
Do not use this option unless you know exactly what you are doing!
