There is/was such mod, and i was gonna use it eventually, but it being an official thing (no need to count on modders to update) it'd make it much easier, and people who cannot or will not use mods, still can get Palm Trees, which would be nice.
Sometimes dropping Coconut when shaken like in the Desert would be great, too.
Maybe if more updates will come again, it could involve something bigger.
I'd love to be able to craft them with like a Coconut, Cactus Fruit and a bunch of Fiber/Mixed Seeds.
Nothing special, but a nice addition, imo. Maybe a newer NPC can give the recipe, like Leo, when he moved could give it when hearts are high enough, maybe maxed.
