In the 2.3 release notes https://access.redhat.com/documentation/en-us/red_hat_3scale_api_management/2.3/html/release_notes/release-notes, we indicate the following:
"Better OIDC capabilities for integration with 3rd party identity providers (Support JWK through OIDC Discovery)"

Per support's feedback, we should make it clear that the integration is limited to the gateway. Proposing the following text:
"Better OIDC capabilities for APIcast API gateway integration with 3rd party identity providers (Support JWK through OIDC Discovery)"

In 2.6 we will release a better interface to integrate with 3rd party IdPs, so that should add further clarification https://issues.jboss.org/browse/THREESCALE-1131
