You are married to the idea that character attributes represents a uniform biological difference in dnd races. They have decided culture, training and individuality(ie varies more person to person, than culture to culture )is actually the dominant factor in attributes.
It just comes down to your personal preference, you like the idea that race is the primary determiner of a character's potential. Many prefer the creator. The big issue you bring up MIGHT be a lack of guidance/lore about the standard culture, for those who want to lean into the tropes of that background. However, its likely many races will come with recommendations of background.
It makes character creation better imo. In the bonded system, +4 attribute points is a pretty major effect, especially in levels 1-10 where most people play.
The primary determiner is still point buy/standard array. Race is in the end just a background modifier which makes sense. You can make a clumsy elf but because elves are naturally dexterous that clumsy elf would still be equal to normal (but not trained) humans. Background does not make sense at all. Why would a noble automatically be charismatic?
