I think it was dependent on getting a new method for passing mount flags
around which did make it in to 5.x. Its probably something that someone
would have to work on, thats all.  For NFS tuning options, though, I'd be
a bit sketch on passing ALL of them back; I don't know if the current
implementation understands which have been changed so it knows to send
them down.
