Sometimes I'd like to think that it prevents misunderstandings. But that's probably very subjective. I'd also guess that just because they feature it heavily on the keynote that a huge team spent the whole year only working on just Emojis. That doesn't mean that there weren't a lot of other teams doing important ground work and internal improvements that are not that easy to showcase on a keynote for a very diverse audience and press.
