Legend
If they have special mechanics that mean say, they are natural diplomats, that is undesirable in the modern game, because it has the message “if you are not born this way you can never excel as a diplomat”.Let me explain it simpler.
Humans, orcs, and elves have different lore, mechanics, and special traits. Half elves and half orcs lore, mechanics, and special traits that humans, orcs, and elves do not have and not in the same combination.
You can say we don't need them. But you can't say orcs and half orcs in 2023 were the same.
So you cut the “born diplomats” from the game. Now anyone can excel as a diplomat.
But by not including something in the PHB or SRD WotC are saying “we don’t want this any more, so you are free to do whatever you want with it”.
