One thing I didn’t see mention of is group membership. Is this / will this be part of the core offering? Being able to map IDP group membership to permissions within your SaaS is powerful, and in my experience highly desired by clients.
So if you're familiar with Okta's parlance, both "Attribute Statements" and "Group Attribute Statements" are returned to you in `attributes`.
