interesting! that would definitely be useful. you don't need a
dedicated new app engine feature, though; you can do it yourself, in
user land. i haven't tested this, but it should work:
class Foo(db.Model):
...
def root_key(self):
root_key = self.parent_key()
while root_key.parent() is not None:
root_key = root_key.parent()
return root_key
