Those are changes to the vnode metadata, not the directory structure. 
We'll do them, but the directory changes have been designed and merely lack 
implementation, whereas the vnode metadata changes will require changes in 
the way the fileserver stores that data and new RPC's, neither of which 
have been designed.  The two sets of changes are orthogonal; I see no need 
to do them "at the same time" or make support for one dependent on the 

Getting a directory format that would be backward compatible with existing 
clients was a tricky bit of work, but I think we succeeded.  Doing that for 
vnode indexes will also be tricky.  This will almost certainly require 
another lengthy design session.  But this is getting a bit off-topic for
