Weak roots are also used with grafted trees for another reason, the tree will carry fruits earlier and more numerous at the start.
A tree with normal or strong roots might carry a lot of fruits after 10 years when it got pretty big, but before it is just a few.
But strong roots also go deeper, so less/no watering is needed, which is why I prefer strong roots, I don’t have to make money with the trees in my garden after all.
