Interesting, isn't it? There you are, and yet none of those dozens are garnering anywhere near the same amount of attention and enthusiasm as jj. And yet, it's genuinely mostly just that -- a novel CLI on top of the same storage backend as git. Sometimes it doesn't take that much to bring about a paradigm shift, I suppose. Just a few new ideas with a great implementation, and there you are -- they've just got to be the right new ideas. That being the hard part.
