I don't like having two onSuccess functions in one WebCallbacks. If we want to
pass a non-pointer value, moving existing CPA<S, T> to CPA<OwnPtr<S>, OwnPtr<T>>
looks the right direction. Let's talk tomorrow.

No, I was confused. I wanted to say

moving existing WebCallbacks<S, T> to WebCallbacks<UP<S>, UP<T>> is the right
direction.

UP may be scoped_ptr in the end, but we cannot use it here at this moment.
