I don't mind the workflow of selecting what you want at a later time, but my concern is with having changes visible to the local repo database automatically. If you like it that way, that's cool with me. But to me personally I'd rather have the filesystem doing snapshots and not comingle fs snapshots with VCS. I can nuke an fs snapshot in a single line of bash if I accidentally leak something, and fs snapshots don't contribute to the slowness of a big repo. But those are problems in regular git and would be even bigger problems in a version of git that treated VCS as if it were an fs snapshot system. But like I said if that works for other people that's great. It would probably work for me if I were a consultant working on a lot of small repos. I don't think it scales to a bigger repo unless the jujutsu repos are completely destroyed every few days, which is essentially what happens to CITC client working copies at Google.
