Hi Howard,
Thank you for reaching out. Yes, the "Detailed Demographics" feature is still not available in AdWords API and we are no longer planning on updating this request. Our top priority right now is to get the new Google Ads API ready for general availability. As such, we aren't planning on adding enhancements to the AdWords API, but we will continue to fully support it, and address any bugs as they are found. For more information on the state of the Google Ads API, please read the blog post
here. If this feature does become available, you can expect it on Google Ads API only.
Regards,
Danica, Google Ads API Team
