Let's look at Tiefling racials:
2 charisma, 1 intelligence
Darkvision
Fire resistance.
A useless non-combat cantrip or the even more useless mage hand that requires concentration and doesn't even have the strength for its single only use which would be to push enemies off elevation.

Remind me again why anyone would touch Tiefling or Humans when these other races are overloaded with far more benefits?
Charisma is virtually useful to a single class in EA...
1.) Charisma is useful for persuasion/intimidate checks, and presumably you want your MC to be the Face when talking to NPCs.
2.) As you said, Charisma is incredibly important for Warlocks
2b.) Charisma will be important for Sorcerers and Bards when implemented. Larian shouldn't change racial traits now, just to change them back when these classes are introduced.
3.) Enemies have fire arrows and vials of alchemist fire, so the fire resistance is pretty good. Especially since AI in BG3 focuses on low-AC characters, of which your Tiefling Warlock is probably one of.
4.) Larian has implemented mage hand incredibly poorly. It shouldn't be concentration and you should be able to have it and other summons out. The solution is to fix mage hand, not necessarily buff tieflings.
...but yeah, humans are a bit underpowered. Or maybe not underpowered, but at least less flashy.
Larian should implement the Variant Human, where you get +1/+1 and a feat.
