I understand that just rebinding SPC is much easier. But we are
supposed to consider other factors, not just the ease of
implementation. And I'm not afraid of code that is somewhat inelegant
and even breaks abstractions, if we provide better, friendlier UI
which breaks less habits. Many Emacs's abstractions leak from many
holes anyway.
