--------------------------------------------------------------
Note that the Kraft implementation adds a bunch of methods that are not usually
needed (like mutability, etc). So, it makes sense to keep and use the interface
and not to combine them. But there may be cases where the methods only exist in
the implementation (and not interface) due to the previous zk implementation.
In such cases, we should pull up the relevant methods so that no casting is
required.
