I do not know why but lot of people think that options added to the emperor are inherited to children/vassals. This is not true (and would be totally wrong from a technical point of view). To start an emperor you only need the –emperor option.
Your configuration (and assumption) is the right one.
If you want to pass options to vassals automatically use the techniques described in the official docs, otherwise each vassal require its options.
