First, I want to point out something Archbishop Lefevbre said:
"I do not say that the pope is not the pope, but I do not say that you cannot say that the pope is not the pope."
Knowing this, I don't think it's important to even mention that you are a sede, much less that it matters.
It's not a matter that is totally set in stone, because the Church has not made a pronouncement. So, there is no opinion, (being loyal to BXVI, doubt that he was validly elected, or that there is another pope in hiding somewhere) that will put you outside the Church. In essence, it's basically the same as believing/not believing in Limbo, since the Church hasn't made an official pronouncement one way or the other on its existence. It's one of those things we have a liberty to believe, since the truth about the situation cannot be 100% KNOWN.
Understanding this, you're going to run into a lot of differing opinions on the subject, and do they REALLY matter? Nah, and you shouldn't MAKE it matter, because perhaps a few people in the world know for 100% certainty what the real situation is, but the general person in the pew, or the scattered traditional priest really does not know. I don't even argue about this issue anymore, because I just say that, "I do NOT know, and I'm not going to even TRY to wrap my mind around it because the conspiracy is so vast, that I don't think it's possible that it can be known at this point, and along with this fact, it does not pertain to my salvation as a Catholic, therefore, it DOES NOT MATTER, as long as you're true to the teachings of the One, Holy, Catholic and Apostolic Faith."
Secondly, one thing many people don't do when they "move halfway across the country" to set up shop in a "traditional" town, is the matter of employment. Now, if you're going to plan on moving somewhere, you had better investigate your employment options first, and make sure you can afford the cost of living and the expense of sending your children to a traditional school. Traditional schools are very expensive. Heck, many people live right in Saint Mary's, and can't send their multiple children there because they can't afford it. So, they live there, but they homeschool. I know people that have moved there from here (Northeast Wisconsin) and they've had to move back because "the grass was not greener," i.e., they did NOT have a plan, they didn't have a job lined up for the breadwinner, they didn't have savings in case things didn't work out right, et cetera.
At one time (in my younger and more foolish early married years) I used to dream about moving there and sending my children to school out there. In my now wiser (narrowly approaching 14 years) later years of being married, and from observing others that have foolishly moved out there only to find themselves back here in short order, I have resigned myself to the fact that the grass is NOT greener, and unless you have some kind of specialty profession, or want to travel to Topeka for work, you're going to fail out there, and it's not worth it.
Just things to consider.
