If you care about such things then don't use vanilla emacs. Use spacemacs instead where I suspect you'll have this out of the box. It's not an obscure port. Indeed in the long run it wouldn't surprise me if we end up with more spacemacs users than vanilla emacs. I've even run across some pages with emacs tips where they take it as a given that you're using spacemacs (the tips only work on spacemacs and the page never qualifies this).

And even with vanilla emacs it's probably a one liner in your config to get vi bindings.
