I feel for the artists whose job it is to draw and organize nearly 4000 little vector images, most of which will barely ever be used to communicate anything.
I'm going to imagine that it's functionally impossible to make a font with full emoji support now unless you're a massive corporation. (Not that it's an issue really, but there's only so far you can push the list of required code points right? You can leave off entire character sets if they aren't used in the target language you produce a font for. On the other hand, leaving off the head shaking emojis is going to be unforgivable for a lot of people that feel like they're being left out because of their phone OS choice or something.)
