I think I recall that Bugnini says the Italian Bishops pushed very strongly both for the transfer of Hoyldays of Obligation to the Sundays,

The deliberation of the synod [of Pistoria] about transferring to Sunday feasts distributed through the year, and rightly so, because it is convinced that the bishop has power over ecclesiastical discipline in relation to purely spiritual matters, and therefore of abrogating the precept of hearing Mass on those days, on which according to the early law of the Church, even then that precept flourished; and then, also, in this statement which it (the synod) added about transferring to Advent by episcopal authority the fasts which should be kept throughout the year according to the precept of the Church; insomuch as it asserts that it is lawful for a bishop in his own right to transfer the days prescribed by the Church for celebrating feasts or fasts, or to abrogate the imposed precept of hearing Mass,—a false proposition, harmful to the law of the general Councils and of the Supreme Pontiffs, scandalous, favorable to schism.
