Not if the goal is to test quality of real datasets, and that was the goal.
Getting this weird information about newer datasets generally outperforming older datasets was more of a side effect of having a dataset evaluation system.
If you're trying to examine AI contamination specifically? There are many variables, and trying to capture them all in a laboratory dataset is rather involved.
For one, AI data out in the wild is "enriched" - it's very likely to be selected by users before being published (human feedback best of 4?), it can gather human interaction like likes/comments, it's more likely to get spread around if it's novel/amusing/high quality than it is if it's low quality, generic and bland. How do you replicate that in a lab setup? On a tight budget?
