> The RelFieldTrimmer has some shortcomings:
> * If the plan contains certain set ops (e.g., UNION(all=false)), even if the
> operator needs all fields for the correct result (CALCITE-3399), it may still
> make sense to apply the trimming to the children. See CALCITE-5051 for an
> example.
> * Same applies for a Sort with dynamic parameters in the fetch/offset, and
> RepeatUnions
> * The makeZeroLiteral logic in trimChildRestore(...) does not work for ARRAY
> / Java types.
