I still think "EENS" is a waste of time nothingburger for 99.999% of people who make it their hobby and/or life's work, main crusade.
I haven't encountered any Trads anywhere in Tradition -- not even in the Indult, which is technically not part of the Traditional Movement -- that encourage would-be converts to stay in a false religion, for various reasons (they can be saved there too, water Baptism isn't necessary, etc.)
Call me down-to-earth or non-intellectual if you will, but my take on EENS is simple. Get baptized, join the Catholic Church or die the death -- the eternal death. It's simple, at least to me. I look at pagan countries and it's clear that the chances of any of those billions saving their souls is about zero if some Catholic missionary doesn't intervene. Even if one out of 10 million somehow saved their soul, who likes them odds? Missionaries are indispensable and crucial to the eternal salvation of a huge portion of the world.
I think those who argue EENS, Feeneyism, etc. should spend those dozens of hours writing Apologetics works, running an apologetics website/apostolate instead. Much more good would be done.

I think actually most people hold this view but the problem is the theologians etc promulgating heretical ecclesiology through docuмents like
Unitatis redintegratio. The ecclesiology of VII percolated for quite some time and it's impossible to truly address any of the bad docuмents in VII without addressing EENS. One of the interesting things about almost everyone is that they correctly identify ecclesiology in general as the biggest issue with VII but don't follow that any deeper. I can even see that you actively identify this because religious liberty and the new "canonizations" all are downstream of the same problem (EENS) but what of it? Most see these docuмents in mostly a vacuum rather than an ecosystem. You could easily say that
all VII docuмents with issues all share the same poisoned water source in that said ecosystem, being Rahnerite ecclesiology. Seeing how the issues started to happen in the 1700s even with Jesuit missionaries being condemned for how they teach concepts like the Trinity to savages and other conversion elements were being played with fast and loose it's unsurprising we are here today.
I actually do disagree with your assertion that Indulters share even a remotely similar view to you; the founding docuмents for
Ecclesia Dei communities accept all articulations of VII, while the classic RnR position sees "error" in these docuмents and potentially heretical teaching. If you look at the official
Ecclesia Dei responses to
TC it's clear this is still the
modus operandi for them because they accept VII as valid and want to coexist with an antichurch/antihierarchy that accepts a heretical ecclesiology. The SSPX classic position is truly that there is a visible Church but the Indult
de facto denies this fact.
This is honestly why XavierSem interested me quite a bit, he held an ostensibly SSPX friendly position but denied the dogmatic fact (a visible Church) that differentiated it from the Indult. I think the SSPX's weakness on EENS is why the Indulters and NOers fit in well there and have transformed that organization. He's part of a greater flood here, and I think this trend is important.
