> Related: https://github.com/apache/iceberg/pull/17736 (closed) proposed routing all projected variants to the row reader because plan-time shredding detection isn't sound, and noted that queries not projecting a variant "are unaffected and still vectorize". This issue is that unprojected case: it isn't unaffected, because the reader builder still walks the unprojected shredded group. https://github.com/apache/iceberg/pull/18121 (open) reworks the same SparkBatch check but still only over projected variants. thank you for flagging this.
