One of the biggest problem for integrations is that Magento 2 supports already depreciated and insecure OAuth 1.0 instead of 2.0. On top of that, OpenID would helped third party apps to be securely integrated to Magento 2 increasing security and transparancy.
Its also adviseble to add in support Keycloak, Simplesamlphp (It has OAuth 2.0 and OpenID plugins) and also Gluu server as open source identity servers.
