No, this is the bug I was experiencing. NFSv4 mounts failing at boot- time (or later when manually attempted) with idmapd failing.
I chased down the location in source of the string "/var/lib/nfs/rpc_pipefs" and found the only place it is hard-coded is in device-discovery.c. I applied the linked patch and the clients can now mount the NFSv4 exports successfully.
