No more foods. Especially sugary desserts when there is currently no ability to craft a toothbrush and toothpaste. Plus last I checked there is currently no dentist villager available to do routine cleanings and fillings for the rampant cavities one is sure to get eating so many desserts.
Partial support. Minecraft has many food items, but not many options for crafting those items into even better stuff. But these suggestions are, as someone has mentioned, mostly clones. Maybe you can change that.
People always say that Minecraft has enough food already, but I see IT as a choice by the person. The ability to choose from a variety of foods to eat. Say someone doesn't like Pumpkin Pie, they can make an Apple Pie. Some people prefer carrot cake over regular cake (I personally do).
I like the idea or being able to start up a bakery or food shop on a server or etc. And being able to sell more than just 3 things because that is all the food there is. You don't see people saying there are too many kinds of food in the real world , so why say it about Minecraft?
