Both vim and emacs have had problems recently in balancing refactoring needs and their traditional architecture and project layout. People are more and more used to contributing to projects with an occasional pull request. However to benefit from this, the projects have to become more accessible to these people.

Vim and emacs are projects that are of special strategical importance to the world. They must not vanish.
