Exactly, I doubt Bishop Gumbleton will be pleased here in Michigan! But Cardinal Maida will have no problem with it.
Our bishop here just sent out a letter instructing the priests to follow the guidelines on purification of the vessels. The priests, of course, were objecting and wondering if they really "had to" do it. (Like it's such a burden.)
I think a lot of it is going to depend on how much the bishop enforces it; as you say, expect zilch from Gumbleton, but Cdl Maida will probably be a different story. It will be interesting to see if the dread USCCB makes any statements on this, although I have a sense that they are losing power, fortunately.
