Yes, that is the kosher way for most commands. It gets a bit tricky for "checkout <branch-or-committish>" that changes its behaviour (a local branch is checked out and the next commit extends it, other committishes like tags and remote-tracking branch tips are checked out on a detached HEAD), and has special rules for a "${BRANCH_NAME}" that is both the name of a local branch and something else. Hopefully (Duy Cc'ed) "git switch" would improve the situation.
