I'm sure the devil will be in the details, but as a broad goal, this
seems reasonable to me.
There's a lot of room for Django to "eat it's own dogfood" when it
comes to the admin interface; making individual views class based,
making it easier to reuse parts of views, and so on. If this sort of
refactoring were to happen, it would seem logical that improved
configurability of these views (e.g., making the "home" view
user-configurable) would be a logical outcome.
There were some discussions at DjangoCon US 2011 about starting a
"Django NewAdmin" as a broad development effort; however, this doesn't
appear to have generated any massive development effort. If this is an
area that you would like to help out, feel free to pitch in!
