Yeah, we have this -- if you check out the docs for the endpoint where you accept a SAML login[1], there's an `attributes` (map<string, string>) that SSOReady returns to you. That contains the contents of the relevant SAML assertion's AttributeStatement.
So if you're familiar with Okta's parlance, both "Attribute Statements" and "Group Attribute Statements" are returned to you in `attributes`.
