Toward a "modern" Emacs

Toward a "modern" Emacs

I will try to say what others have said again.

Yes, Emacs is mostly a development platform — and API for that development platform is Emacs UI.

That's the same issue Firefox developers faced and the same issue which made Chrome developers to only offer very limited extensions API: if you give developers an option to change, basically, anything in your app… then suddenly all possible changes in the app become impossible.

That's why, ultimately, what we have now, today, is not Emacs 28, but, in reality Emacs 1.28: the major part of Emacs version number was dropped years ago because you couldn't radically change anything in Emacs.

You can only extend it, not change it.
