You can easily flip the question around, though. Who benefits if OS X keeps this key binding? A few people who still use some arcane, 30-year-old text editor. And the rest of us are stuck wondering what the heck just happened when we accidentally press one of these shortcuts.

I respectfully submit that those who expect their OS to act like emacs as a matter of design rather than historical happenstance have plenty of other options out there. But I also understand that it's not fun to have the rug pulled out from under you in this way.

Everyone benefits by the possibility of learning useful shortcuts that work in stuff like safari text fields -- no matter the bindings, and no matter how old -- as long as Apple isn't adding more modern ones.

I don't use emacs, but i did learn ctrl-k, ctrl-y and some others.

Not using emacs here but regular user of bash, zsh and various readline-based tools (python, irb, mysql...), ^A ^E ^K ^Y are extremely useful, everyday, so it's a boon to have them working in every text box in the system.

This seems to imply you shouldn't have keyboard shortcuts at all. After all, the principle of least astonishment says that if you hit a key combination you didn't intend, nothing you didn't intend to happen should happen.
