i'm not opposed to the idea, but what I have in mind is that each
install can set up defaults into the bottom layer.
Each install profile can then set up defaults which are in a layer
above the module
I also believe we need a code based set of defaults. kind of like we
use $conf now.
Not sure where that would fit in.

I kind of like it. =)

Well, i'm thinking we could pull it off in a few simple api
functions. It would make
a lot of modules simpler. take the content settings for instance.
