I feel like the lack of an initial empty commit is really a failure to match the intuitive graph model. Clearly there should be an arrow corresponding to "adding the first files". And that arrow needs somewhere to go from and to. Hence, `git init` should always start by creating an initial commit object referring to an empty tree. A side bonus of this would be that since the initial commit is empty it has a fixed id. Suddenly, all git repositories have a common ancestor, and you can merge any two random projects together without losing history!
