That's not modal though. You could make it modal/sticky with e.g. god-mode, evil-mode, or others, but essentially its a single shortcut (yes, it uses two keys instead of one, but that doesn't make it modal: try pressing Ctrl and afterwards pressing n like with esc h for vim, I don't think it'll work...)

Org-mode and magit are modes in the sense that they are different environments, not input modes. You won't have a good time trying to update your calendar using magit, and reverting the latest commit is going to be a challenge from within org-mode. These are different tools.

I'd say once again, emacs can be as modal as you like, more or less exactly like vim, or it can be non-modal.
