IsSummaryQuery Implementation Hidden

[russell-thompson]

Is there a reason why the DataSourceLoadOptionsBase IsSummaryQuery member is hidden with the [EditorBrowsable(EditorBrowsableState.Never)] annotation and is not supported in DataSourceLoadOptionsParser? This appears to facilitate requesting only the TotalSummary information which would be a useful feature when no data rows are needed.

I'm concerned about providing an override in my API to enable this capability if it is hidden because of known issues.
