Evil mode: it's the basis of spacemacs. If you don't want the complexity of spacemacs and you don't mind writing a bit of elisp to get your bindings working, it's worth looking at.

Am I missing something here? That's like an asthma drug whose side effect is shortness of breath.

You're missing something. Spacemacs defines a lot of keybindings for many plugins and so on. Evil only defines the basic Vim keybindings. If you want more, you have to write it yourself.

Of course it does! :).
