I see the playtest normalizing mixed-parentage characters. The "Half-Elf" and the "Half-Orc" are no longer weird. Now mixing is something that all sapient species can and do.
I see the opposite. Rather than normalizing it "Thanks to the magical working of the multiverse Humanoids of different kinds sometimes have children together." "wonderous pairing" - Implies to me it is weird, and unusual, while they have made it clear all sapient species can do it, when it happens it is "magical and wonderous", not something that happens every time different species get busy. Though half-elves and half-orcs are the more common of these pairings, so are less weird.
