Well, not completely. There is now this option "nohide" on /etc/exports which does this. Another useful thing we use a lot here. With knfsd you still have to authorize (export) separately each local mount point (unfsd used to automatically authorize all the underlying tree), but with this option you can mount just once and go down into directories which are on different filesystems on the server. A very useful feature, specially while autofs is not able to do cascaded mounts. We use this for some sysadmin tasks on clients, which export their root to their server.
I recognize the need for a robust NFS structure on Linux and understand that some restrictions on features might be needed for that. But all these features are quite nice and useful, so I hope ways are found to implement them in robust ways. Regards,
