“...are still bonded to the church but not to the Roman curia...”

This is impossible. It’s the Curia that determines how the sacraments are administered. You cannot practice Roman Catholicism in any meaningful way for very long by being indifferent to the actions of the Curia. These people are Protestants without calling themselves Protestants.
Sadly,the Church,including the Pope and the Roman is in a “fine mess”.
