> 1) Batch to row converter doesn't propagate columns correctly because they are not in
the schema.
> 2) Then, even if it did, the current VrbCtx model of ACID column propagation only works
with VectorMapOperator. Regular MapOperator has no such context; the reader ends up storing
the vector in some fake temporary ctx. I left a TODO that combined with a fix to (1) could
fix this instead of disabling it.
