When you talk of ultra-conservative bishops or just ultra-conservatives, these are purely political labels. Conservative and ultra-conservative Catholics are simply orthodox Catholics. Orthodox Catholics are those of us who were taught our Catholicism prior to Vatican II.
We were instructed that the Faith and Morals as taught by the Catholic Church was inviolable and unchangeable. Along came V2 and overnight the Mass changed considerably; that which could never be changed; changed. With the New Mass the Catholic Church shot itself in the foot: if the unchangeable Mass could after all be changed beyond recognition then every other 'unchangeable' dogma and doctrine was also up for debate.
Very few Catholics were aware of what went on at V2 but the reordering of Churches and the new Mass signified that a sea change had occurred in Catholicism: Modernists were in the ascendency: a new broom was 'sweeping clean' thousands of years of Catholic belief.
In heaven nothing has changed.
