I find it interesting that both games of this variant between Kramnik and AlphaZero ended in a draw. That suggests to me that we would quickly see the same problem in the variant as we do now. The question would be, how long would it take for humans to catch up? My guess is a couple of years, until the variant has to be changed again (That is, mostly draws in high level competitions). What are other similar games that have a higher level of variation? Go comes to mind. How about we increase the size of the chess board to 9x9, while keeping the same 8x8 setup? That sounds like a number of variations more than no castling, while still keeping the same feel.
