[keycloak-user] Keycloak U2F

Hi, we tested Keycloak U2F from Stian Thorgersen (https://github.com/stianst/keycloak-experimental/tree/master/fido-u2f) and are highly interested. But there are still a few open questions like e.g. self-registration similar to OTP or the fact, that it needs writing access to LDAP (user repository) to enable "U2F registration" action on a user. Is there a roadmap available when U2F will be available for keycloak? Regards, Ramon
