The question was more did GNU Emacs caught up, or did the folks that cared about XEmacs moved into better pastures?

(X)Emacs was relevant to me, because there was still no IDE culture in UNIX land back then, like on PC and Amiga, and between vi and (X)Emacs (vim was yet to be a thing) definitly (X)Emacs, when UNIX IDEs finally became mature enough, I moved on.

If it is installed, I will use it, but won't go out of my way to use it daily as back then.
