Those PHB edits are rather deceitful.

Now, some of that stuff is racial and clearly a result of their lineage. Age, size, darkvision, land speed. Some of that is not like Language and Alignment.
And this is true of every single race you listed. You took the first sentence, then posted only the ASIs and ignored everything else underneath that sentence. So, unless you want to say that Half-elves Biologically know a random language from any race, or that Halflings are biologically pre-disposed to Law, then you need to recognize that not everything under that sentence is meant to be true of the race as a biological fact.
Bingo.
It's important to note that racial traits are a mix of biology, society and personal ability. An ridge elf's +2 Dex can be justified as biological, but what about his proficiency in bows or cantrip? An elves proficiency in Perception could be viewed as biological, but what of a half elves two skill proficiencies?
It's interesting that there is a lot of flap about the ability score mods, but no one is concerned about the loss of elfishness that is trading your weapon proficiency and Perception skill as part of the Tasha rules. [emoji848]
