Yes, Prince Constantijn was born as a member of the Royal House and - in my eyes - falls under the not-retroactive effect of the new Royal House Act 2002. With other words: like his aunt Princess Margriet, he will remain a member of the Royal House until his niece Queen Catharina-Amalia abdicates in favour of the next generation. Practically said: Constantijn will remain HRH Prince Constantijn of the Netherlands, Prince of Orange-Nassau, for the rest of his life.
His aunt Princess Margriet is popular, well liked, approachable, but like her sister Princess Beatrix you will never see her in infotainment shows like DWDD, Jinek or Op1. Out of the question. Still this distance did not affect her popularity at all. I wished Prince Constantijn and Princess Laurentien would keep that wise distance as well.
Of course the rest of the extended royal family, like Maurits van Oranje-Nassau, van Vollenhoven or Jaime de Bourbon de Parme or Irene van Lippe-Biesterfeld... Allez... They are furtherer away from the King and there is no ministerial responsibility for their words ans actions.
