IdrisSeabright: I am surprised that you don't see the obvious value in posting publicly about this issue here. Every public post about this makes it harder for Apple to ignore that the change negatively affects real users. I did _also_ post to the private Calendar feedback link (which is not what you have linked to), but it's worth re-examining your opinion about why there isn't value in writing here publicly.
My original reply to this is targeted at someone who has the power to fix this issue. You are obviously not that person, and, frankly, you seem like the kind of exasperated Level 10 forums user who I generally avoid, so feel free to simply ignore the reply I've posted here, for the betterment of reading this on page 25 of 25.
