Christoph certainly doesn't like Rich ACLs, as do many other people.

But the deal block was that the patchset:

 - totally duplicated the VFS level ACL handling instead of having
   a common object for Posix and the new ACLs
 - did add even more mess to the already horrible xattr interface
   instead of adding syscalls.
