Biology is one thing that makes them unique. I would say their particular connection to certain gods matters and their shared history (nearly not totally universal with its cultural implications).Except that biology is what makes races unique. By making ability scores selectable you remove nearly all uniqueness from races.
take one thing away and you take some but not all away. But I do think it changes party composition and dilutes things a bit.
Not a fan myself but it does not totally wreck the game. Not sure why they felt e need but think it less campaign and mechanic related than some are saying
