I honestly am not. I am genuinely interested. Everytime there is a post about jj I'm about to try, and then I see a comment like yours, saying "with jj you just use the intuitive syntax `jj git push -r '(trunk\(?.\).x#@ | @@.^)'`, which is a lot simpler than knowing about this weird concept of stash" and it makes me think that maybe, I'll try again next time.
