I perfectly agree, still I'm not happy with deleting the local routes for the temporarly orphaned secondaries without notifications and just re-add them again later. I think we should either prevent the deletion of the local routes by rewriting their preferred source address during promotion or explicitely announce the temprary orphaned secondaries as down and up again in order to have the local routes deleted/re-added in a clean way.
