Review comment:
> I don't think we should let each invoker to decide whether to make the
data type not null, because in current codebase, we should always do that, make
the decision everyone is error-prone and hard to maintain.
I agree making the same decision over and over again at multiple location is
error prone and hard to maintain and that's what I want to avoid.
