I'm not entirely sure I understand what you mean by losing status. For people who have immigrated to Canada, once they've immigrated, status is irrelevant. We know that the spouses and dependants of a skilled worker principal applicant look very similar to the spouses, partners, parents, and grandparents of people who enter in the family class.
One of the things we might want to be thinking about is this comparability of individuals across classes who are in some sense similar. What I'm saying is that spouses and dependants of the skilled workers look like the spouses, dependants, and parents coming in through family class.
