I think the "incompatible" was more in the dvorak sense, which I believe is that whenever you are on another computer, it most likely won't have dvorak.

For jujutsu, it's fine on your own computer, but you probably have to use git in the CI or on remote servers. And you probably started with git, so moving to jujutsu was an added effort (similar to dvorak).

> For me at least, it's not hard at all to switch between Dvorak and Qwerty.

Sure, but you had to learn both. And what benefit did you get from learning Dvorak?

I feel the same with jujutsu: I have to learn it on top of git, and I don't see a lot of benefits from knowing it.

>And what benefit did you get from learning Dvorak?

More comfortable typing, less wrist strain, etc. It's just a better layout.

Yes - this puts it perfectly. I am a very fast typist - I can type ~156wpm in QWERTY. When I was a kid and learned about Dvorak, it was tempting - but I already typed so fast that learning another keyboard just seemed like it would cause "misfires" in my brain - and virtual keyboards are all QWERTY.

Same deal with jj vs. git. I've learned git. I've used it for 15 years. I'm proficient with it. I'm sure jj is better - but I'm not sure it's better enough to be worthwhile.

It doesn’t support submodules. So no, not totally compatible.

Reminds me of how I started using Git when it was up and coming: It was the best Subversion client out there and no one knew I was using it!
