some among us, like me, don't like to see monsters become player races. And yes, for me even Drow and Duergar are already pushing it.
Why can't people just play an ordinary elf, halfling, gnome, dwarf or human? Why does it have to be something outlandish like Tieflings or Dragonborn or even worse, a monster race?
Yuan-Ti are monsters for a reason, same as goblins, kobolds and every other monster race someone may ask to play.
That's pretty much how I felt about this stuff when I first encountered it in NWN2. That said, BG3 already lacks any kind of wonder with most outlandish monster and races feeling very pedestrian. They might allow me at this point to play as an Observer and I don't think it would make a noticable difference.
