> As of https://github.com/google/styleguide/commit/7a7a2f510efe7d7fc5ea8fbed549ddb31fac8f3e the Google Style Guide no longer forbids use of mutable references for output arguments, and actually encourages using them when the output argument is not optional.
> This puts arrow c++ style out of sync since we've continued to police toward usage of pointers for output arguments. We could:
> - keep the ban and note this as a deviation from google style in [development.rst|https://github.com/bkietz/arrow/blob/392af8aa999f940ab8fd61684820b2c6d89f7871/docs/source/developers/cpp/development.rst#L74-L75]
> - open JIRA(s) for deprecating/replacing pointer-output APIs where applicable
