alt Hacker NewsI'm having trouble understanding the value of this and most other supposed advantages of jj I'm seeing. I'm trying to pinpoint if it's because 1) my workflow doesn't need jj's fancy stuff, 2) I've gotten so used to `git`'s "flaws" that I don't notice them, or 3) the git porcelain I use (magit) does a good enough job at managing the flaws.
If you need to build on something that requires changes from 3 open PRs, can't you just start a new branch from main, merge all 3 PRs into it, and get to work? As changes are applied to the open PRs, you can rebase. Obviously that might cause some merge conflicts here and there, but as long as the PRs aren't super overlapping, they should still be manageable. If there's a ton of overlap between 3 open PRs, that to me sounds like a problem in the workflow/plan, which must be dealt with regardless of the VCS or porcelain.
For me, it wasn't so much that jj enabled things I couldn't do before, though there are some things. What it enabled was me doing the things I was doing, but in a more easy way. This also leads you to do things that you can do, but sometimes avoid because it's a lot of work.
