Wait, (from the first link) the hiking emoji isn’t real either? Could have sworn there was one with a guy (and a girl one) taking a step while holding a walking stick/staff.
How do the emojis get selected/assigned? It feels like tugging on that thread might help resolve this. They don’t just randomly show up; someone decides to assign a unicode value, artists create the images for many platforms and emoji packs/fonts, code interprets the unicode and replaces it with the associated image.





Luckily each unit has a number that indicates the floor and each floor probably has a floormap near the elevator, so you won’t have to go knocking on random doors until you find the person.
Same thing for making deliveries in cities of several million. If there’s an effective addressing system, it’s usually trivial to find the destination, or at least to get very close to it and switch to “ok wtf is going on here with the last bit of this address?” mode.
