> It would be useful to be able to append a Scalar (and/or ScalarVector) to an
> ArrayBuilder. For example, in
> https://github.com/apache/arrow/pull/9621#discussion_r587461083 (ARROW-11591)
> this could be used to accumulate an array of expected grouped aggregation
> results using existing scalar aggregate kernels
