I'm all for reimagining the concepts that go into version control, standing on Git's shoulders. However, I think this is way too close to normal git for me to think it's useful. It might be simpler in ways, but it feels more complicated in others. For example, branches are pretty much the simplest concept you can think of in Git currently - just pointers to commits (referenced by name). Trying to think of them as separate lines of development actually makes me a little nervous that I would clobber some history somehow.

Anyway, that's not to discourage the effort - this is how we move development forward.
