Imagine you have something like a horse. The horse has a head and a tail and it wears a saddle. The head and tail are fixed to the horse (like scenery, but conspicuous = "false"). The saddle may be removed (like object). You want to be able to EXAMINE and describe these. As the horse can move around, it makes sense for the head, tail and saddle to be part of the horse. When defining start_at for the object, Ctrl+Space allows you to select an object, but if you do, you get an error saying, "Object is defined as starting inside other object "id:horse", but that object has not been defined as a container". You have been discouraging us from using containers, so is this sort of thing possible or not?
