Asymmetric default behavior of git stash

Hi,

is there any reason why the default behavior of git stash is asymmetric?

When I save my current state with 'git stash save' it saves the worktree changes and the index changes (and resets both). When I restore the state with 'git stash pop' it restores the worktree changes, but not the state of the index. Your work preparing the index is lost.

Although this behavior is documented it is kind of unexpected. From a save-restore mechanism I would expect that the default behavior would restore the state as it was before the save. So I would expect it to either save and restore the worktree and leave the index alone or save and restore both, the worktree and the index.

Regards
