^Fwiw, there is one way I've recently learned of at my Catholic university for pushing through the Vatican I ecumenical mess. If you read Catholicism and Democracy by, I believe, Chardin, it demonstrates that the entire ultramontane vs Gallican squabbles that culminated in Vatican I (which actually was a compromise on the ultramontanist side, that wanted an even higher view of the Pope than was affirmed) was entirely contextualized in the long 16th century with the emergence of the modern nation state, appearance of so-called "spheres" (public, personal, religious, etc.), and the collapse of the complex ancien regime. Vatican I was the Catholic Church's attempt to adapt and respond to this new world they suddenly found themselves in, which is why they ended up in conflict with Napoleon, supported less-than-virtuous proponents of the old ways, etc.
This means that there is hope for Catholics to reinvision the papacy through a full understanding of the historical context of the two Vatican councils, and there are Catholics that do just that. My grad professor being an example, saying that it is great for Catholics who want to break away from papal centralization, universal jurisdiction, etc. There just need to be more willing to push in this direction, I think.
