Wouldn't you agree that the entire discussion goes into a direction that reveals that it might simply be a better idea to require commands that want to have per-worktree refs to do that explicitly? I mean, it looks to me that the harder we try to avoid that, the more problems crop up, some of that as serious as my reported data loss. I do not see any indication that trying even harder to "protect" commands from knowing that they are running in one of many worktrees is making things easier. To the contrary, I expect that direction to hold many more awful surprises for us. The same holds true for the config, BTW. I really have no love for the idea to make the config per-worktree. It just holds too many nasty opportunities for violate the Law of Least Surprises. Just to name one: imagine you check out a different branch in worktree A, then switch worktree B to the branch that A had, and all of a sudden you may end up with a different upstream!
