returnProperties argument does nothing in CRM_Contact_BAO_Group::getGroups

This doesn't just affect the API, and that doesn't even use it yet. But I wanted to use it for my new addition to the SOAP API to get groups. However, it appears to not actually do anything beyond indicating whether or not you want the member_count property.

SOAP::Lite chokes on some of the returned data if you just return all the properties of the group(s). I'm assuming it's some of the quoted SQL stuff.
