In the case of the use for arch rendering the import of other scene elements, trees, cars etc! The option to package these via "pack and go" and import as the same but the import acts as in internal separate scene, ie the object is in a folder style sytem of objects and materials that do not intermingle with the main scene elements and only edit when that folder is opened. Visability against other scene objects also controlled via hide other! It would just I feel free up working within the main "subject scene" and leave all other elements uncluttering!
