I have used emacs for decades so I do not see the need for a big restart, but your question does remind me of something RMS said years ago. I cannot find the exact quote, but the essence of it was that any editor that offered the programmability of emacs was worthy of the name regardless of its keybindings, etc. In that sense I do not believe there would be any problem with emacs following the model of Fortran; it can look and behave quite different, but at its core it has to be open and accessible for the user to extend and adapt.
