Humans, tieflings, dragonborn, dwarves, etc. are all PC races and can be enemy humanoid types, so moving goblins, et al. to fey, gnolls to fiends, etc. so they can escape the "these are people so go ahead and kill them all without remorse" issue is garbage.
If there is a problem, focus on the true problem, and stop trying to gloss it over with other things.
Anyway, that is my rant about it--sorry if it isn't quite coherent.
Its perfectly coherent, and it makes obvious that Wizards is just hiding the issue because they dont have the stones to tell the players 'yeah, actually, you are killing other sentient beings, deal with it as its an Elf Game'.
