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.
