Why did it? Emacs is a great development environment. It allows you to focus on the code and supports debugging right next to your code, same as an ide. It is an ide.
Emacs lacks some features of xcode/eclipse et al but in exchange it has power they lack. Why shouldn't it gain some of their features?
(I am assuming you loled because you considered emacs weaker. My apologies if I got the sense backwards).
I've been programming in emacs since 1992, 2014 was the year I finally gave up and started to move into IDEs (having to target android was the primary motivation for using something else, but I'm rapidly getting spoiled, and am going to shell out for clion once it's done).
There's stuff I miss about emacs, and I'll keep using it for text files and r code and other stuff (it's still my primary python editor until I get around to trying pycharm), but by and large I think I'm done with it for c/c++.
