Yes! For the case discussed in the article, I actually just wrote a comment yesterday on lobsters about the 'evolog': https://lobste.rs/s/xmlpu8/saving_my_commit_with_jj_evolog#c...

Basically, jj will give you a checkpoint every time you run a jj command, or if you set up file watching, every time a file changes. This means you could recover this sort of thing, assuming you'd either run a commend in the meantime or had turned that on.

Beyond that, it is true in my experience that jj makes it super easy to commit early, commit often, and clean things up afterwards, so even though I was a fan of doing that in git, I do it even more with jj.
