[keycloak-dev] 2 mechanisms to configure UserFederationProvider

Currently we have 2 mechanisms to configure generic UserFederation providers. 1) The "old" way, which is using the simple list of strings - UserFederationProviderFactory.getConfigurationOptions() 2) The "new" and more flexible way based on ConfiguredProvider. Should we remove the old way for the Keycloak 2.X ? If yes, then maybe even for 1.X we can deprecate UserFederationProviderFactory.getConfigurationOptions() to notify people that it will be removed in future versions? I know there will be more changes, but if we know at 100% that this one will be removed, it's maybe not bad to deprecate even now? Marek
