I tend to think you’re right about that. And frankly, I don’t think there’s much of an excuse for it. Or for hand-holding or even the orans position for that matter.
And that leads to my :twocents: in this thread:
The usual argument in favor of tolerating such innovations is that the rubrics, or the GIRM (or whatever), say nothing about them. But, both of those are
positive documents, meaning that they instruct what
should be done at a particular time, not what
shouldn’t be done. It takes a negative document for that.
When dealing with a positive document, one has, I think, to read between the lines. For an absurd example, let’s say someone comes to Mass and decides to say the Institution Narrative in a very loud voice. Neither the rubrics nor GIRM says anything about it, but they
do say that the Institution Narrative is to be done by the celebrant(s). If it had been meant to be done by the congregation, the document(s) would say so. IOW, it seems to me that if something isn’t specified, it really shouldn’t be done.
