In addition to this introduction of the Zonai, I've found it interesting that the latest games are focusing so much more on the singular goddess (or demi-goddess?) Hylia, rather than any mention of Nayru, Farore, and Din. They've also really pumped the breaks on anything Triforce-related. Other than the royal family crest itself, there's only really one very brief allusion to the Triforce in Breath of the Wild that I can think of. Maybe they felt they were using the Triforce as a McGuffin too often.
