JJ might be good (this article couldn't convey why in the "What is jj and why should I care?" page) but it's not 10x better than git, so it will likely die. Sorry, nothing personal, Mercurial/hg was a little bit better than git and died too. Network effects.
What has a change is ast-based version control.
You adding a feature to a function that uses a struct I renamed shouldn't be a conflict. Those actions don't confliuct with each other, unless you treat code as text - rather than a representation of the logic.
Ending merge conflicts might make a new version control 10x better than git, and therefore actually replace it.
Did you confirm that the network effects are applicable here before posting that?

The difference is that I can (and do) use `jj` with existing git repos today without needing anyone else using the repo to change what they're doing. There's no need to replace something when it can exist alongside it indefinitely.
