Agreed -- as a Deaf person who uses visual languages to communicate, it's allowed me to actually begin to express myself using a set of pseudo-language visual elements. Some of them roughly map over to ASL expressions; I am looking forward to when they add ASL-specific emoji, or ASL language support, or even hands in the new animoji.
There's no way to say this without being insensitive, but this reminds me of a grade school joke without a punchline - "how do you write in sign-language?" Can you help me better understand what ASL language support would look like or what that would mean to you?
If you consider how ingrained and emotionally significant that expressions in your native language are, animojis with hands - which will take that emotional significance and put a cute spin on it - is going to be massive.
