AIUI, A root user still can. The users krbv5 credentials will
generally have been cached to storage. (though i suppose one could
mount that storage via NFS and use root_squash, but that's little
protection.).

Unless NFSv4 has dealt with the problem above, it isnt much protection
from rogue root users.
