I suspect that, when William comes to the Throne, we are going to see a lot of changes, one of which is limiting Counsellors of State to working Royals only. I also think he'll move to have Harry's titles stripped and Harry and harry's descendents removed from the succession. I'm very certain William has a list of reforms he wants done to the monarchy.

Removing Andrew from the succession makes sense, and I doubt any realm of which Charles is King would object to it.
