> With Pope Francis reviewing and moderating a lot of traditional doctrine, and with a large group of those within the church opposed to it (particularity those from the first world), I could see this edict being "modified" going forward
There are many "liberal Catholics" in the world, and organizations dedicated to "modernizing" Catholic doctrine. They're pushing and hoping for things like ordaining women as priests, allowing abortions, gay marriage, etc. [1]
But they'll never succeed. Doctrines can't be changed because they're inherently immutable. [2] So by definition it's impossible.
Yes, there will always be polls trying to demonstrate that doctrinal change is possible given a strong enough public voice [3], but this is and will always be impossible. All those polls do (and I would argue are meant to do) are make people think they're on the right track with their dissent, and that it's not really apostasy, just a harmless opinion.
