My understanding is that it's all bred to be easier and faster to grow. Flavour isn't first in the value equation.

And longer shelf life. And flavor isn't in the top 10

Yes. Flavour isnt the main factor, its easier and faster growing, not spoiling, basically all the factors that are what a supermarket asks for. Here in southern europe flavor is the main concern. The flavorless produce doesnt fly here because nobody would buy that crap. We have standards. When I was living in the US I was shopping in wholefoods only and buying the most expensive varieties of the produce, and it still sucked xD
