Products get made to the standards of the pickiest customer. The condiments and sauce industry has the (((same situation)))[1] going on. If Costco went poof tomorrow the change would only be a marginal one down to the standards of the next pickiest customer worth optimizing for which is probably only a hair's breadth away. If Costco was trying to drag the standards way up then farms would raise separate stuff for them.

[1] Many condiments are Kosher not because the recipe inherently is, but because it's easy to do without much downside so doing so pencils out handily. I couldn't resist the parenthesis joke.
