Review comment:
I have no problem delegating to `DebugConfigurationListener` instead of
duplicating code in `ValidatingConfigurationListener`, but in that case I
suggest also to "un-deprecate" `DebugConfigurationListener` because it is just
confusing if that class should continue to be used or not.
