I hope not. Watching the Emacs ecosystem evolving over the years, I'd wish that most things were not default or built-in but came in packages, and Emacs was a tiny, extremely small core. Packages outside of the Emacs core develop faster, evolve better, foster communities around them, have greater flexibility of choice - where to host them, how to license them, how to structure them, etc. Evil-mode, Magit, Projectile, CIDER, etc., they are all great because they were developed outside of the Emacs' core. I can only imagine how Evil+plugins would've slowly decayed with endless email threads on the Emacs-devel mailing list, where RMS would've annoyed everyone asking "why are we trying to build Vim in Emacs instead of Microsoft Word, I've dreamed about WYSIWYG, and you guys are ruining it...".
