I want a variant of this where I make a worktree that has no ability to push anywhere including its parent. Instead the parent worktree pulls from it automatically. That way I can run some sandboxed workflow that might arbitrarily corrupt the work tree, possibly overwriting everything in it and symlinked from it, without losing data.
Then you'll probably want a clone; which will cost in more space. Just remember to remove the remotes.
You could always use an overlayFS with the main (non-worktree) repo as the lowerdir (and then remove the remotes in the overlayFS), but that relies on you not trying to keep working on the git repo at the same time.
