Make a branch follow working copy commit?

[johnwheeler]

Hi, what are the thoughts on an option where the branch follows the current commit (or even better get set to @-) after every commit?

I suppose I could write a shell script to do that, but I'm wondering if that is against the ethos of jj or something I am missing that it is bad to do that / prevents me from doing other things.

Thank you. I love jj

We have #2338 for letting you do jj commit --advance-branches (and presumably some short version of the flag, such as -b). We probably don't want a config option because then jj new main; jj commit would always move the main branch forward, which is probably (?) not what you always want.
