This is true, but the issue I was concerned about is that memorizing datasets is not fun, so games should be designed so that dataset memorization provides no advantage, so that competitive players aren't forced to waste their life memorizing datasets.
Solving this issue also naturally solves the game variety issue.
As for variety, there is still the risk that chess engines might be able to produce a single long consensus main variation for each 960 position, and so that even if people can only memorize one variation, everyone could memorize and play the same line.
