Baking, I think, was introduced in Get to Work, and isn't a base game skill, so I'm not sure how baking could be incorporated in a Farming Pack. Not everyone would have the original pack that includes the Baking skill. I also don't think EA would put a second Baking skill in this new Farming Pack since there is already a pack with baking. So as much as I loaf the idea of harvesting wheat and producing flour I don't expect it to be included in Farming Pack. (Unless there is a new Breadmaking skill--which is a super trendy activity among millennials, so maybe Sims-appropriate)
Similar thought with using honey on the Farm: it is harvested from beekeeping boxes from Seasons. This is a big maybe, but in the Farming pack they might give us honey from a tree with a beehive in addition to Beekeeping boxes (for players who don't own Seasons). That way people who don't have Seasons could still make nectar with honey.
But as far as what we want or expect, I think we should try and come up with objects, activities, and harvestables that are independent of other packs. There are some players out there possibly that will only have the Sims 4 base game and this new Farming Pack and nothing else. Let's brainstorm for them!
