This brings the power of the index up front using a proper mental model without talking about the index at all. See for example how all the technical discussion has been evacuated from the git-add man page. Any content to be committed must be added together. Whether that content comes from new files or modified files doesn't matter. You just need to "add" it, either with git-add, or by providing git-commit with -a (for already known files only of course). No need for a separate command to distinguish new vs modified files please. That would only screw the mental model everybody should have when using GIT.
