I'm struggling to understand the problem this solves for me. I can see in the abstract why this might be useful, but in practice I don't see the problems. For me, jj represents a massive step forward from git in terms of usability, usefulness, and solving problems I actually have. I think the next step forward for version control would be something that works at a lower level, such as the AST. I'd love to see an exploration of what versioning looks like when we don't have files and directories, and a piece of software is one whole tree that can be edited at any level. Things like LightTable and Dark have tried bits of this, it would be good to see a VCS demo of that sort of thing.
