Reread your comment. I misunderstood the first time round. You presented a theory that Apple implemented Emacs keybindings for Cocoa text input widgets not because of Emacs per se, but rather, mainly for consistency with bash. It's an interesting theory, but without a history lesson backed up by sources it's still a theory. For the record I don't underestimate how much effort Apple puts into system-wide consistent behaviors in macOS. <s>Also, zsh's default keybinding mode is Emacs mode.</s> (Of course, you did mention that.)
