1) Are there any benefits in replacing a personal private project git repo with jj? I usually just commit straight to master in order to just not to lose the changes and be able to roll back. 2) Are there any pros in doing so in a project with many large binary files (3d models, images)?

You don't replace. jj is backed by git anyway.

You can switch an existing git repo to jj by using:

jj git init --git-repo my-repo

I think (but CANNOT PROMISE) that just removing the .jj folder will bring you back, but definitely take a backup of .git before you try this in case I’m wrong.

No that is correct when in colocate mode (which is the default mode). Simply removing the .jj folder will "de-jj" the repo entirely, but will leave you in a headless state. Simple to fix with a `git switch` though.

If you are _not_ in colocate mode, the .git folder is located _inside_ the .jj folder. So worth checking!

Okay but why would they use jj when they do trunk-based dev

[Jenk]

I do trunk based dev. My colleagues prefer git. I still prefer to use jj.
