I mean, that's only ever been a dream in the emacs community. Vim might have toy plugins for other stuff, but by and large people use it to edit period. As it should be, isn't the whole UNIX philosophy to do one thing well? If I want email or a text browser in the CLI I'll use dedicated, better, faster programs, each on a tmux pane that I can use instantly with a keyboard shortcut, rather than wait for slow emacs buffer to load.
