Again, we hear the profoundly silly suggestion that the Church's current discipline of denying Holy Communion to 'remarried divorcees' could be replaced (of course, only on an individual basis) by a (needless to say) very tough period of penitential discipline, followed by readmission.
We tried out all that sort of daft stuff in the Church of England. My recollection is that when I was ordained to the Sacred Priesthood in the 1960s, those involved in a 'second marriage' in which one of the partners had already been validly married to somebody else were supposed to be subject to the discipline of being excluded from Holy Communion for six months.
This was a dead letter. Neither bishops nor parochial clergy were prepared to risk the fury ... oops, I mean Hurt ... of those who were supposed to be invited to undergo such discipline.
Believe me, we tried such ideas in the C of E and they simply proved to be a brief preliminary step towards the automatic acceptance of all de facto unions.
Now there is a Church of England in which a 'Catholic' bishop, one of the leaders of the rump of Forward in Faith which stayed in the C of E, who, himself divorced, has 'married' the divorced wife of a priest. And he stays in post, ministering to those who are supposed to have secured such a good deal enabling them to remain in the C of E and to 'flourish' there with full 'Catholic' integrity.
With much help from the old Adversary, the dear old C of E got, decades ago, to exactly the place to which you are trying to lead the Catholic Church. I agree that it is jolly sensible for you to follow the Church of England's example and teaching, if that is where, with the same august help, you are determined to go.
But you seem to me to be (1) bewilderingly naive in not being aware of the destination you are in fact heading for; (2) unendearingly arrogant in imagining that you are the first people ever to have had these Brilliant New Ideas; and (3) thoroughly obtuse in not spotting who it was that crafted them, and where.
