I wonder if we could promote multiple worktree from a hack to a supported feature. What I have in mind is when you "clone --separate-worktree" it would create a .git file that describes separate worktree:

gitbasedir: /path/to/the/original/.git name: foo

HEAD, index and logs/HEAD would be stored in /path/to/the/original/.git/worktrees/foo/. GIT_DIR would be set to .../foo/, GIT_OBJECT_DIRECTORY, the new GIT_REF_DIRECTORY (which covers root for all refs/, logs/ and packed-refs) and maybe GIT_HOOKS_DIRECTORY are pointed to directories in .../original/.git/... though.

This allows all worktrees to be aware of the others and locking could be implemented so that no two worktrees check out the same branch (or they can, but the other becomes detached if the ref is updated in this worktree)..
