Actually, this modification wasn't present in v1, but once it was introduced in v2, it made sense on its own: to eliminate the redundant traversals of worktrees when renaming a branch, even if the branch isn't HEAD in any worktree. Therefore, I think the change can also be seen in another way: the increased ease in the next modifications is a beneficial side effect of this patch.
