It was a mistake that the Unicode people started to add emoji of their own at all ever in the first place.

My understanding is that emoji were originally added because they existed in other preexisting standards. They should have kept it at that. Now we get public discussions what concepts are important enough to “deserve” emoji, which is a stupid, pointless discussion that could have been avoided if they had not started doing that. We were able to communicate just fine before emoji were a thing.
