Yes, the original use case for chaining: e.g. adding an author to a 
paper without having to manually give it a blank node name or repeating 
a predicate.

There are generally a number of cases where the markup is much more 
pleasant and readable with @instanceof.

That's interesting, although surprising and different from what I've 
seen, where folks want to "add a type" quickly, e.g. a calendar event, a 
business card, etc...

   <div instanceof="cal:Vevent">
      <span property="cal:dtstart"> ... </span>
      ...
   </div>

If you had to give the event some random identifier, I believe that 
would be worse and error-prone.
