I think not. Edit is to edit files in the terminal. What kind of files do you expect people to edit in the terminal? Most certainly files that would benefit from colors, not prose.
A lot of authors, myself included, want a "distraction free" editor. Its a whole over-populated market segment.
Prose thrives in the terminal. Ice and Fire was written in WordStar, as just one popular example.
I met someone recently that still uses WordStar. Yes I'm serious. He runs it in QEMU on FreeDOS. He's a writer for a living.
