As I see it, the answer to your questions is that the teachings of the German bishops and the Polish bishops speak for themselves and lockstep uniformity of  pastoral "enforcement" in these individual situations as dictated from Rome, beyond the teachings found in the apostolic exhortation,  is  unnecessary.  These teachings express the need to move beyond throwing diverse sets of circumstances into one-size-fits-all black-and-white categories.  

The insistence on a simple "yes" or "no" answer is legalistic cross-examination, not an invitation to dialogue.  And continuing focus on the relationship between the Pope and the four cardinals who seek to continue a public debate on the matter at their level is unedifying, to say the least, IMHO.

Hang in there Tridentinus. Seriously.
