Description
This PR reverts #24882. This isn't a breaking change because #24882 isn't yet released.
The upcoming Iceberg 1.9.0 makes row-lineage and default-values required in their V3 spec.
Shipping deletion vector without supporting those features will be troublesome.
I think we should wait until the V3 spec has stabilized.
