[keycloak-dev] Import Clients?

It looks like there is a partially-implemented facility to import clients from admin console? client-list.html has this: <a id="importClient" class="btn btn-default" href="#/import/client/{{realm.realm}}" data-ng-show="importButton">{{:: 'import' | translate}}> But I can't find any reference to the "importButton" flag, so it looks like it is never set and the button never shows up. Can anyone tell me more about the state of this feature? Is it supposed to work?
