Please don't go 1.x or make evolutive recipes :)

Recipes changes are awesome: kind of adaptability test. I think it should even be in the game by a way or another. Like at some point in the game, some of them should become obsolete, or technical progress would change the proportion of ingrediients needed. So it would be challenging to make an autoregulating factory, instead of a fixed-flows one.
