I am not sure how you can tout food spoilage as an "improvement"
Because it is. It's the first part of maintenance for things in Eco and as such helping with economical issues on servers that are one of the main reasons why players leave early - when they have nothing more to do, because market is simply saturated by a few, given there is no need to ever replace something.
Food spoilage requires planning and gives better sale chances given there is no way to just queue up orders till christmas. It's fully within the idea of the game as well to make overproduction have consequences.
If you don't like it, you can configure the multiplier in a way it won't be relevant for you.
