Number 1 is just a bit too overzealous due to the number of officers
I doubt anyone here wants decisions for obscure historical officers. Keeping it limited to the 50 most popular ones sounds a reasonable idea.
and also the fact that due to the nature of CK2, the owners of those provinces would have the officers since they were children anyways since they have to be in someone's court upon being born.
I don't understand what you're saying here.
