There's no inherent or logical reason that it should.
If it does, it will be a coincidence like an individual man becoming a sede.
The SSPX, founded by +Lefebvre had a position on the Crisis which was good enough to last -- and thrive -- from 1971 to ~2003. Let me underline that point -- the SSPX position was so prudent and Catholic that the majority of Traditional Catholics chose this position. Let's not forget that.
And yes, numbers DO matter when you're talking about a body of Traditionally-minded Catholics trying to keep their Faith. What does it mean when the majority of good Catholics -- who pray, practice mortification and penance, are detached from the world and luxuries, who don't care what people think (human respect), who think carefully, etc. -- decide to go with the SSPX position?
My premise, though, is that you start out with a body of good-willed Catholics trying to find a solution to survive this Crisis with their faith intact. Some sedevacantists would suggest that the only good Catholics were the ones that went sedevacantist. But that is dogmatic sedevacantism and schism, which I and (any other sane Catholic) reject.
Once you grant that all Trads started out being of good will, it certainly says something when the lions' share of them went with the SSPX.
So there is no reason why a Catholic, or thousands of Catholics, couldn't decide right now to stay with that position. Why should +Fellay get to ѕυιcιdє-bomb a perfectly good position on the Crisis?
He doesn't have the right.
Just because +Fellay fell doesn't mean that everyone adhering to +Lefebvre's position NECESSARILY has to fall, or that the position is INHERENTLY untenable. I'm sure many have wondered about that in the past couple of years -- but it still doesn't make it a fact.
