...at first it appears that down-rev files might not need to be treated 
as nest-mates on the basis of their InnerClasses attributes. They have 
access bridges to communicate.

But someone might want to "inject" a dynamically generated nestmate into 
a self-nest of an old-rev top-level class then which communicates with 
nested classes via bridges and expect from this dynamically generated 
class to have access to private members of nested classes too. So 
treating down-rev files' InnerClasses attributes as nestmate metadata 
might be necessary.
