No argument here. You make a fair point. But why not try to improve upon a proven technology? To make a product appeal to a wider audience? Not everybody likes a smaller socket goggle.
I would venture that on a pure running website there are purists that ask the same question about max cushion shoes. Some athletes chose comfort and performance over minimalist.
There is a benefit of wider vision in a bigger lens goggle to be far wider and better optics than the smaller two piece goggles. This helps in the open water or in the pool. MP wore a goggle this summer that has a curved lens. A technology innovated for larger lens goggles but now in a smaller two piece goggle. A great innovation.
Everybody has a different preference. There is a lot of swimming outside of the most elite levels of competitive swimming.
