Well, I phrased my question the other way because I suspect such cases will be found, but I may not have found all of them. Some thoughts on why I might wish to take a hand in the decision: 1. the client doing pnfs might behave badly due to a misconfiguration or outage, yet behave acceptably using ordinary nfsv4? 2. restricting the client to ordinary nfsv4 might be desirable for non-developer troubleshooting or other configuration work?
