For those who like it, sure. But it's been done. To death. (For me.)A perfectly valid approach, popularized imo with Eberron like settings.
It's too close to the racial xenophobia that is prevalent in so many older fantasy worlds. Those worlds further racist tropes. Normalize them. Inspire people to defend them as valid.
I care not for them. And I really hope that future D&D lore moves away from race/species being the primary conflict generator.
