I wanted, but it didn't compile due to needing a newer Rust compiler, than is available in my Distro. And the tutorials I found told me to run the equivalent of curl|bash, which I will not do. I don't felt like learning a new language/ecosystem just to try out another VCS, so I said, it's not worth it, I wait until it is available in my distro.

So actually no, and you have a point. :-)

I often just read "this is hard in Git" and think isn't this just this command? JJ has some nice features, but what appeals to me seems to not to be that hard to add to Git, so I will just wait a bit.
