----------------------------------
    Fix Version/s:     (was: 1.28.0)
       Resolution: Not A Problem

It is supported. Just not by default. See [SqlConformance#isGroupByOrdinal|https://calcite.apache.org/javadocAggregate/org/apache/calcite/sql/validate/SqlConformance.html#isGroupByOrdinal()]. Closing as 'not a problem'.
