React needs a new object for its hooks when you change them. We need to modify those objects, so deepClone + direct mutation on the clone bypasses a lot of annoying immutable object creation bs. ppl just destructure the whole thing anyways, which is actually also pretty slow

React hooks don't need to add the entire object to their dependency array; they can specify only the properties that are actually dependencies of the logic contained in the hook.

You should check out immer for that use case ("modifying" an immutable object with imperative code).
