Usually when I see a recipe in a crafting grid, items that are oreDictionary-ed together -- such as wood types -- the recipe grid will cycle through them, informing me that these recipes are members of a set. This is fun, in that I can explore the possibilities and chase down theories.

But the grid in the engineering table presents only one possibility as if that's the only acceptable version. The only clue that is happening is closing and re-opening the crafting grid can present a different member of the set of all possible recipes. From the player's perspective this represents a loss of information when compared to the majority of experiences with modded Minecraft.
