@TheOliphantintheRoom can we be BFF? The fact that a male consort cannot be a king because King is intrinsically senior to queen bothers me a LOT. But I am usually told to "be quiet dear" when I bring this up. To my mind, it just shows how far our language has to go before we can consider it even vaguely gender neutral.
I'm pretty sure the Queen consort IS known as Queen WHOEVER. The phrase, "King George and Queen Mary" seems to rattle around in my head as one I have read/heard a lot from books/shows regarding them. So Katherine will be Queen consort, Queen Katherine but she won't be "The Queen".
Yes re Camilla - she was supposed to be Princess Consort as a sop to Diana fans but it's not clear that will still happen and that she won't be queen. I get the sense she likes the stuff she can choose but the big formal stuff she's less keen on. But if Philip can retire, no reason she can't too surely?
