I never needed it directly and I wonder if it was not a case of 
over-engineering that helped zope's community fragmentation.

I don't know why grok did not succeed.

it's just an application specific security "model". some pages (or parts 
of it) are merely for admin roles (which have a group of people 
associated). In other cases, it is the data (records, which belong to 
the creator, or corresponding team, or related maintainers. Has it 
happens, the roles are part of the data of the application and naturally 
used to manage the data or pages or parts of it. For the pages, it is 
hard-coded. Each page has associated a single Python script (business 
rules) that produces all data as a single class which includes 
attributes like isAdmin, isEditor. Nothing general purpose.
