I tried out with a tiny project. It is the muscle memory built up with Git that kicks in and wish that JJ does it. I went through all the raw mistakes and doing things the hard way with Git, that, my mind plays trick trying to use JJ with the Git mindset. For now, I have mapped all of my Git aliases to JJ equivalent. But I would like to learn it the right way and do it the JJ way. This is going to take time, I’ll go slow.
I really recommend just ripping off the band-aid and using jj "as intended". It took me only a day or two to adapt, and a week to feel like I am now a jj native. It's really a tiny cost to pay, and way less than the overhead of maintaining a bidirectional mental mapping between jj and git.
