I think that the donut examples are too small and limited to be interesting beyond the issues presented by nested data.
The TPC derived data like nations and regions provides a bunch of other examples such as grouping, joins and correlated sub-queries. Creating additional examples when we already have what we need doesn't seem all that important. I can be proved wrong if somebody instantly comes up with examples that are donut themed and provide all of the necessary examples. It should also be noted that we are going to wind up with examples from TPC-DS which a realistic snowflake schema and volume. Restating all of those examples in terms of donuts is a whole lot more work than restating two files. So we are eventually going to have to give up on donut purity. Why not now?
