I wonder if there was a way for other clients to detect apple and translate their 'watergun' into a new emoji while keeping backwards compatibility on all other clients. Or another way for all vendors to push back against Apple is for all agree to not render the new emoji from Apple devices. Its too late now but one of these two would have been a good solution in 2016 to push back against Apple's nonsense. I guess since this is also used in SMS there is no way to properly detect the client its coming from?
