The whole emoji idea is running out of hand. Out of billion's of people on the planet there will always a few (=millions) complaining that their race, their house, cars, their pets (and currently, their poo) aren't represented.
And they will never be, because the development of ancient languages has learned us that there are just too many objects on the planet to be uniqiely depicted by symbols (or icons, for that matter) which ultimately lead to characterisation in words.
I hope we don't have to go through that learning curve again.
I suggest that we disassemble the Unicode Emoji Subcommittee and offer them a decent job in rural farming or alike where they can relive the development curve that they strive for.
