More of a question than a request. This measures the same thing as parquet_struct_projection.rs at a complementary altitude, schema-level narrowing versus expression-level pruning, so a schema_narrowed group inside that file would put the whole story in one place and land PR-3's fix next to the assert it flips. The trade-off is a longer file and generalizing the helpers (register_parquet versus ListingTableConfig::with_schema). Fine either way; just worth a look before committing to a second binary.
