I don't like how they did it. Tasha's Cauldron fix is not a good fix for the issue at hand.
Ideally, race would be renamed to species, and grant physical traits only; background would be renamed to training and might give a +1; a new culture/background thing dealing with the location and themes the character grew up in would be added, also granting a +1; and classes would grant a +2 in their chief stat.
This would definitely require overhauling a few other things, and would indeed increase party power level, but that can be compensated for.
