Yes, but sometimes you want to override a template from another
application, like grapelli[1]. The AppDir template loader searches in
order of installed applications. By putting grapelli in front of
contrib.auth, you're able to override the original admin templates.

I'm not sure I know what you mean by "pruf link". If you provide
keyword arguments to a function, you have no way of telling in which
order they were provided, because all you get is a dictionary (which
has no meaningful order):
>>> def a(**kwargs):
... print kwargs
...
>>> a(a=1, b=2, c=3)
{'a': 1, 'c': 3, 'b': 2}
So you can't use that syntax and keep ordering. If the template
example doesn't convince you, take a look at the "syncdb" command. You
need a way to specify in which order in which custom SQL or fixtures
are loaded from each application. I don't see a one with a dictionary
or keyword arguments.
