I think the point of this was to remove the genders, right? To avoid offending the people who get offended if genders like male and female are acknowledged to exist?
If I want to ask a friend out for drinks I just need a generic drink-like icon, like a cocktail glass. I don't need all the variations between beer, wine, cocktails, shots, toasting glasses, bottles, and so on. It's the point of a hieroglyphic anyway, to convey a more articulated message through a simple image.
The same with all the nonsense with genders, scarves, disabilities and skin colors. Let's have a round, genderless face of a color no one has, and move on. Nobody needs to identify with that anyway, it's a symbol like the gas pump on your car's dashboard.
