But did you know that recently it has been reintroduced and now affects NNUE evaluation?
Contempt is back as "Optimism", an idea originally conceived to make Stockfish avoid trivial draws and look for moves that made progress on the position all things being equal. However, it brought significant elo!
And this wasn't just elo against weaker opposition, since Optimism stockfish is playing better moves than without it, as if positive contempt was beating contempt 0.
So the new paradigm remains, because, again, if you analyze a position with white, and then with black, each side will like itself slightly better because of optimism. Each side will like to avoid draws because it's more optimistic about the position.
As I said before, a position has a white's eval and a black's eval and you better have analysis files for each side that can disagree about the backsolved eval on the position, because it depends what side you are and how optimistic you should be, otherwise optimism wouldn't work
