The original report was against Git v2.12.2. I have since tried v2.12.3, v2.13.0, and the next branch. All exhibit the same symptoms.
Even if you ignore the original scenario for creating the problem, if I do a 'rm -rf' or 'mv' of a tree that contains within it worktrees, that should not break the use of Git with worktrees that live elsewhere nor commands that don't require a repository.
