WhiteEagle12 has mentioned which would be unnecessary, but more products, including such tree fruit trees and what could be made for cooking with them, is always fun to play with.
The more crops, trees and such would be implemented, the more we can do in SDV, especially if they're gonna be more useful than JUST cooking(like cooking dishes that have nice buffs and/or healing, close to Fruit Salad, maybe?) and such in mid/late game.
Early game i'd like to see Stamina/Health-only consumables, so one of these trees could be useful for that.
Those are more balanced, as they'd restore one of the two instead of both, but not weak, so that common stuff like Green Algae and such wouldn't be more useful than them.
And using some for new quests would be cool, like more furniture and such as rewards, making late(r) game not being too bland.
