Composing Store make typescript type unwrap and different

[defghy]

In defineStore composing function, type is right

The ReturnValue of defineStore(), type transfer to specific object, which is not right

I cannot use the object as BoardData

BoardData transfer to specific { boardId: ''...}

[defghy]

In some research pinia.d.ts，this is difference between UnwrapRef and ShallowUnwrapRef in 'vue'

UnwrapRef

ShallowUnwrapRef

Maybe ShallowUnwrapRef is more reasonable here?

source d.ts

(pinia?: Pinia | null | undefined, hot?: StoreGeneric): Store<Id, S, G, A>;

export declare type Store<Id extends string = string, S extends StateTree = {}, G = {}, A = {}> = _StoreWithState<Id, S, G, A> & UnwrapRef<S> & _StoreWithGetters<G> & (_ActionsTree extends A ? {} : A) & PiniaCustomProperties<Id, S, G, A> & PiniaCustomStateProperties<S>;
