I think the time control was 10 +2s

Taking the Rook is the one move blunder. The recapture on c6 is necessary. A superficial stockfish analysis asserts that White is a bit better after this, so perhaps chalk that up to openings research by Caruana or his support team. The idea of Nf3-e5 coupled with Qd1-b3 is known of course, but perhaps not believed to lead anywhere.

I doubt it. The Rxa7 idea is well-known. There are quite a few examples of it in my database, such as the games below. I'm pretty sure I saw a "find the winning move" position featuring it a few months ago.

Miniatures at the highest level are virtually unheard of thee days.

You cannot consider any game played at a time control of 10 +2s to be "the highest level".
