[keycloak-user] Keycloak Reference Token Support

I want to know does keycloak have support for Reference/Opaque token. I have found one feature request which is still in open submitted for implementing reference token fetaure i.e. KEYCLOAK-1719. Today i came across "KEYCLOAK-2738" which talks about problem related to aud is missing from reference token.Can someone confirm, whether Reference/Opaque token feature is provided by keycloak if yes then please provide reference point to do configuration to generate "Reference/Opqaue" token.
