It's a bit a joke, but not too much: the next step will be full integration with editor's undo/redo mechanism, which in the end could be seen as a log-based storage. Because that's the trend I've seen on the (little) new ideas from the VCS world.

If you enable the watchman integration, then you actually get very close to this: your current change’s evolution log and the repo operation log will have every change which was persisted to disk. There are tradeoffs to that, of course, but it’s a very powerful capability—and notice that it’s something that would be a huge pain to cobble together somehow in GitHub which Just Works in Jujutsu. It falls cleanly out of making the working copy a commit.
