So 2000 every 5 seconds as opposed to 1000 every 5 seconds. This is
surely better than returning an incorrect "directory does not exist"
response to almost every NFS user who upgrades. And it will be almost
everyone: maintaining servers on older versions of RHEL and upgrading
clients to recent Fedora is normal.
Or the F-12 clients can change the default back
to v3 by either
setting the Nfsvers=3 variable the NFSMount_Global_Options section
in the /etc/nfsmount.conf file, or set the '-o v3' mount option on
the command line.

But they are all pretty unpleasant. The user gets an obscure error
message that indicates nothing to them except "NFS is broken".
They then have to either export root from the server or edit their
fstab.
I'm not sure I agree with the "obscure error message", but yes
the
client will have to change when mount to a older Linux server,
only a Linux server btw...

Really? Why not? What you are proposing to is indistinguishable to a
user from breaking NFS. I can easily see it.
With all new release of Fedora (or
any OS for that matter) there are always
some pain threshold people have to go through. I just see this is one
those thresholds..

Me too. So, let's see how we can do that without making Fedora more
fragile.
I can't agree with this more...
