Import was always intended to allow proceeding without adding new packages so that a run that builds packages only for say nightly can still import & extend the stable component without adding packages into that component. This release actually makes that work by allowing the repodef debglob to not match new packages, if a previous import succeeded. Not matching anything without an import or an empty import will still produce a fatal error.
