Emoji can be seen as a bait for implementations to support under-represented or ancient scripts as a side effect. In fact, emoji worked so well that we now have a universal full non-BMP support everywhere. For example, MySQL used to have the cursed BMP-only utf8 charset aka utf8mb3! It lasted until everyone started to complain about emojis.
