If I may...

One of the main reasons for this directive was to allow 
the administrators to streamline their class list.  
Prior to this directive, you would have had to split up 
the file systems into multiple classes to achieve 
"parallelism".  Thus, you would have say 15 classes for 
one large client.  Additionally, any new filesystems 
wouldn't be protected unless you added it to one of 
these classes or created a new one.  ALL_LOCAL_DRIVES 
provides a level of protection that we didn't have 
before.  

1.  Restart of failed filesystem only, not the entire 
class.  (when using multiple streams)

2.  new file systems are covered 

3.  Ease of Adminstration, streamline the class list.

So while some of the base functionality is the same as 
/ with cross mount points, configured properly it 
becomes so much more.
