Review Comment:
this means "without" or "ignoring"
([link](https://dictionary.cambridge.org/dictionary/english/sans) to
dictionary). This term is used in core calcite in a few places:
* `SqlTypeUtil#equalSansNullability(org.apache.calcite.rel.type.RelDataType,
org.apache.calcite.rel.type.RelDataType)`
* `RelTraitSet#isDefaultSansConvention`
* `RelDataType#equalsSansFieldNames`
* `SqlValidatorNamespace#getRowTypeSansSystemColumns`
