Why not some form of user self-registration and admin management tool as well? I see a facebook connect in there, which helps, but a pure cake-based user reg/management system would go a long way towards a faster 'out of the box' experience.
And Django Admin? I've since stopped my work on app_skellington in order to work on https://github.com/josegonzalez/cake_admin. It isn't complete, not by a long shot, and php's syntax makes it difficult to use a DSL without going outside the language into something like yaml files, but it will do.
Bake doesn't generate css, it generates view scripts. The default CSS is supposed to be over ridden by your own style sheet. Django-admin is like a gimped version of bake, it's actually closer to Cake's auto scaffold.
