Few people from the Shinobi World who came to this world had eaten Devil Fruits.
Aside from Orochimaru and Kakashi, no one else had eaten a Devil Fruit yet.
After all, Devil Fruits were exceedingly rare and were known as treasures of the sea.
And it was not certain whether a Devil Fruit would suit a particular person.
Take Haku, who possessed the Ice Release Bloodline Limit. If he were given a Flame-Flame Fruit or a Magma-Magma Fruit, then even though those were powerful Logia Fruits, they would not suit him particularly well.
The combination of ice and fire might seem powerful, but it would certainly be inferior to having Haku eat the Ice-Ice Fruit.
Compatibility between a Fruit and its user was crucial.
If Hashirama could eat the Forest-Forest Fruit, the boost it would grant him would be terrifying.
Hashirama Senju's Wood Release was immensely powerful, but it lacked that final trace of vitality and agility. If he could eat the Forest-Forest Fruit, it could allow Hashirama Senju to break through his limitations and truly enter the Six Paths Level.
Therefore, even if one discovered a Devil Fruit, blindly eating it was definitely not the best choice.
But Kaguya Otsutsuki did not want to let this opportunity slip away.
If she missed this chance, then even if Konoha encountered a suitable Devil Fruit next time, they most likely would not give it to her.
Moreover, Kaguya Otsutsuki did not really consider the consequences. Otherwise, she would not have chosen to ambush Isshiki Otsutsuki back then, seize the Divine Tree's fruit, and eat it.
Unfortunately, Kaguya Otsutsuki's gamble did not yield any particularly powerful Fruit. It was merely an ordinary Zoan Fruit.
If it had been an Ancient Zoan or a Mythical Zoan, it might have been of some help
