I found it useful. It's like a guided tour of the Django models layer. This implementation is not useful to me personally, but I wish I had the breakdown (i.e. the onion description) when I started hacking on the internals. I'm still very into relational databases, and I do a lot performance tuning in that space, so I'm interested in how Django translates to vendor-specific code. Although that was not the ultimate purpose here, it was a necessary discussion, and I got something from it.
