> Currently the new IQv2 interface allows applications to query state stores using subclasses of the Query<V> type. Unfortunately there is currently no way to check that the template type of the query matches the type of the relevant store the query is executed on. As a consequence stores have to do a set of unsafe casts.
> This ticket is to explore ways to make the query interface type safe where only type mismatches are detected at compile time.
