1.8.9 versions music&sound sound subtitles settings

Hello, I am contacting support because I want to say my opinion and feedback about 1.8.9 version. Why there's no sound subtitles settings? Why I can use them/ turn on? That is very disrespectful of deaf people because I can't even play minecraft normally. I don't see sound subtitles. Please fix this problem. Thank you for your time.
