This is actually the purpose of the change.  With the prior behavior, 
there was no way to spell "I haven't filled/don't intend to fill this 
slot".  The first time your template expanded a macro, the contents of 
any "define-slot" would be copied into a "fill-slot".  Thereafter, any 
change to the macro's "define-slot" contents would not be reflected in 
your template unless you deleted the "fill-slot" element and re-expanded 
the template.

Now, the "slot" attribute acts as a placeholder, allowing you to see 
each slot that you haven't yet filled.
