Err, you mean to say that root-NFS only appeared after knfsd ? And 
that knfsd was absolutely flawless since day 1 ? :-)

Cluster nodes have usually a small number of software packages 
installed. Most "core" packages (like core-utils, grep, gawk, etc.) 
don't need locking. As / doesn't see itself much writting (which 
happens usually in /var and /tmp, but those can be mounted 
separately), NFSv3 vs. NFSv2 doesn't make much difference either. So 
what's the problem with using unfsd in these conditions ?
