That's the part I don't understand -- why are the RichACL patches being 
rejected?

Everyone loves the simplicity of mode bits (including me) until you run 
into things like the need to automatically create home directories on an 
NFS-mounted filesystem or security situations where, for example, you 
want users to be able to edit but not delete files, and then you're kind 
of stuck listening to your Windows colleagues propose a Storage Spaces 
solution.
