[keycloak-dev] deprecated removals in future

We're accumulating deprecated metadata in models and data model. Eventually we should draw a line in the sand and say we will only support migration from a certain version to current. i.e. Keycloak 2.0 would only allow migration from the last 1.x version. We need to clean all the old stuff out prior to product. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
