I would be cautious about using words like “deafening silence”, or reading into some possible motive to not wish to be rigid.
Every time the Vatican goes a couple years without reaffirming Humanae Vitae, the media interprets this as “deafening silence” (i. e. backing away from a previous position).
Each time a bishop goes through a year addressing some topics, but not topic “X”, the media will conclude that the diocese does not wish to be rigid on topic X; (thus it is ok to just do it).
I will gladly stand by my comment of “deafening silence”. I can’t say that there have been formal petitions to the proper dicastery to correct this issue, but there have been people who have sent letters to the dicastery complaining of the matter. How I know? They have been quite proud to announce publicly that they sent the letter.
Additionally, I kind of doubt that no bishops have ever inquired concerning the matter, particularly in light of the fact that the USCCB atr one point formally considered petitioning Rome for specific permission for people to use the orans position during the Our Father. That was withdrawn, but I seriously doubt that Rome did not know the USCCB was considering the matter - anyone who thinks there is no back channel between countries and Rome, and various dioceses and Rome is naive as to how things move within the Church. And to add to that, there have been a number of papal nuncios to the US - and I seriously doubt none of them have ever broached the matter quietly.
What the media does or says is irrelevant to the matter as it appears pure luck that anything ever comes close to being reported accurately. Humanae Vitae was one document, and it is not periodically revised; the GIRM, on the other hand, is periodically revised, and that is where the matter would be addressed. It (hand and arm issues) has been going on for something like 50 years; so it is not some small matter occurring in some backwoods isolation.
Contrary to the belief of one of the individuals who posts regularly, there are two philosophical approaches to law - Germanic and Mediterranean (and this comes from a law school class I took), and last I looked, the Seat of Peter is still in the Mediterranean area of the world. And the short stated difference between the two is that the Germanic approach to law is “whatever is not permitted is forbidden” and the Mediterranean approach is “whatever is not forbidden is allowed”.
The specifics of the comment about not being rigid were the words used by Cardinal Arinze which were published as to a response to a dubium submitted by then Cardinal George of Chicago. They were Arinze’s words, not my interpretation of them.
I don;'t have a dog in the fight. The arm gesture which often accompanies “And with your spirit” has aggravated me for decades. Hand holding does not bother me - I am perfectly fine either way. And I often use the orans position in private prayer and generally not during the Our Father in Mass. I tend to agree with Archbishop Chaput when he published a letter in Colorado - it is neither forbidden nor required, and both sides need to treat the other side with charity. He apparently was sick and tired of having the matter addressed to him by various people in his diocese.
