It's weird to be building an Emacs clone nowadays. It's fairly clear that Vim and Emacs _both_ lost the editor wars, and VSCode has come out on top. That's not to say either Vim or Emacs are dead or will disappear, but building a clone of a niche editor is risking dooming the project to being a niche within a niche.
