False. You need to call `jj branch set -r@ XYX` manually which can be a PITA but you only need to do that once you push. Or there is `jj git push --named XYZ=@` which moves the branch.

False. The branch subcommand has been removed. You have to use bookmarks now.

Ok, you need to call `jj bookmark set -r@ XYX` (or `jj b s -r@ XYX`), so what?
