Are you concerned about the index only, not unstaged worktree changes?

In this case, keeping a reflog for the index may help, and it would
somehow fit into the overall concept.

Otherwise, we would basically need a full stash before a hard reset.
That's not the first time where we could need a distinction between
"command run by user" and "command run by script". For the former, we
could allow overriding default options, re-aliasing internal commands,
adding expensive safety hooks. For the latter we can't.

It's just that we don't have such a concept yet (other than checking tty).
