The issue is this.
Point Buy allows you to purchase from 8 to 15. But it does not consider racial bonuses.
So, an Elf gets a +2 Dex and then you buy 15 and the racial pushes it to 17.
This has been a subject of concern for many in the TTRPG for literal decades though it's been more heated in the last 2-5 years. The release of Tasha's Cauldron of Everything allows you to instead choose a +2 to anywhere and a +1 to anywhere so that capabilities are no longer tied to species. It also allows you to switch out racial proficiencies for other equivalent proficiencies. (Like trading a Weapon Proficiency for a Tool Proficiency).
This means that the difference in races with Tasha's now comes down to things like Darkvision, Fleet of Foot, racial spells, and the like... or just have +1 to everything like humans do.
I much enjoy it, but do not expect to see it in BG3 as this is a thing that came out after Larian started work on the game and... well... companies like this tend to be slow to adapt such things and afraid of rocking the boat.
