They were simply not a necessity. They were only used to apologize for teamkills really. I never saw a useful one, so there's no real need for them to still be there. And they aren't.

Yeah those things were great. You could always let them know you were sorry and this could prevent teamkilling/voting of someone. My friends and I also used to use these for messages and such. Good times.
