I've just created https://issues.jboss.org/browse/KEYCLOAK-890. If you'd like to look at it that'd be great as we have loads of work atm, so not sure we'd have time ourselves. One thing to note is that we'd have to start with a POC and review it first. I can't guarantee that it's something we'd actually add either.
