That will never happen in "Happy Catholic Communities".
They would ignore the changes and in the end, the "Power Players" would throw a hissy fit.
No one would police them and things would remain status quo.
You don't know that no one is going to enforce the changes to the liturgy that Rome is likely to make. You are assuming that the neo-Modernists will remain in control of most dioceses and parishes but that is not likely. The radicals who imposed their modernist agenda on the rest of us after Vatican II are starting to die off and they are being replaced by bishops, priests, religious, and laymen who are more orthodox than they are. The modernist revolution has peaked and is now losing steam. The reform of the reform will help hurry its demise.
